You definitely treated yourself with an amazing Christmas present, Walt @luftwaffe-birdman
Is a resin printer comparable to a 3D printer, at least the detailing of those guns is fantastic.

Those printed Ma Deuce's look MUCH better than what comes in the kit. Personally I have fired the .050 caliber on many occasions. They had several different variations of it in service at the same time. The ones that look like your parts were mainly used while mounted on a vehicle, or they were used with a tripod when it was deployed by Infantry troops. The ones used in the waist gunner's positions were also very close to what you have made. They used the "butterfly" trigger assembly and the twin hand grips. Other variations of the .050 were used with a breech mounted electronic solenoid that was connected to the aircraft's wiring. When activated, the solenoid would cause the MG to fire.

I am VERY impressed with how these bad boys turned out... The details are incredible. Here I am standing next to the .050 mounted in the Port side waist gunner' position in a B-24J.

Here is a better close up of the .050 MG. You can also see the different colors in use here. The fold up door was painted "Bronze Green", and the rest of the nearby interior section was "Interior Green".

This next picture was taken from just ahead of the bomb bay, while looking forward. I you look very close you can see the cockpit. These planes are cramped inside, even though they look so big from the outside.

This is a decent picture showing the instrument panel. The red box on the top right hand section of the IP is what they called the "panic button". This would activate a series of small explosive charges when pressed. It was used with a timer, and allowed the crew to destroy the aircraft if they thought it would possibly end up in enemy hands.

This is a picture taken from directly behind the pilots seat. This was part of the Flight Engineer's position. Notice the "Bronze Green" color.

This next photo shows the "cat walk" inside the bomb bay. The bomb bay was left in a natural clear anodized aluminum color on this particular aircraft. This particular photo was taken looking aft. You can just see part of the ball turret.

I have a bunch more pictures stored on my cell phone. This is just a tip of the iceberg. Hope this helps. I do have more photos coming up soon.

Here are a few more pictures I had taken and stored on our computer.
This is the throttle quadrant.

The rest of the pictures are on my cell. I will post up some more pictures of the bomb bay soon.
One of these days I might just have to treat myself for one of these printers too. The parts you made using yours are incredibly detailed.

Here are some more photos from the B-24. Going back to your .050... I think that your comments about it are spot on. A good portion of the weapons receiver is hidden by the MG mount. Some of the late war crew served MG's had an electronic sight. It had the gunner dial in the wingspan of the aircraft he was going to be firing at, and it calculated the wind age and elevation, theoretically improving the chances of getting a hit. Here is a decent picture I took from inside a B-17G. This photo is showing not only the mount, but also the gun sight.

This next picture is a close up of one of the bomb release shackles. I took this photo from inside "Witchcraft".

These smaller shackles could be added to the bomb rack as needed, and they also had a provision for manually releasing the bomb. These were interchangeable between various aircraft.

This next photo shows a partial view of the Starboard side forward bomb racks. This picture was taken while I was looking towards the rear, and Port side. This is the front bomb bay. You can see the various holes in the rack. This allowed the shackles to be connected at various spots. The diameter of the bomb, combined with the total bomb load weight, was the deciding factor as to how these were positioned in the rack. The aluminum colored thing with all the rivets is the underside of the wing.

Here you can see a replica 500 pound bomb in the forward bomb bay. This would have been on the Port side, looking aft. The rear section of the bomb bay can also be seen. The rear bomb bay also has a replica bomb in it, and it is visible in this photo.

This shows you how the bombs were attached to the shackles. This is a bomb located in the Starboard side, looking forward.

This next picture shows more of the cat walk, and the "almost" empty bomb bay. This is the forward most Starboard side bomb bay. You can see a replica 500 pound bomb suspended on the forward Port side rack.

These next two pictures show you more of the bomb bay and how it looks with several 500 pound bombs hanging in the rack. Up first is the Port side, looking forward. This is the forward bomb bay.

Next is the Starboard side, also looking forward, and also the forward bay.

Since you mentioned the small portable oxygen tanks, here is a picture of one for you.

Each one of the waist gunners had a large wooden ammunition box, which was loaded with a belt of ammunition. The rear turret had a box on each side of the fuselage. This is a picture of the ammo box for the tail turret, on the Starboard side of the fuselage. The Port side was almost a mirror image of this side.

These boxes had a series of small holes in them, that allowed the gunner to make a quick visual and see how much more of the ammunition belt was left.

This is the "catwalk" going from the rear turret, to the waist gunner's positions. If you look closely, you can see the ball turret. I took this picture looking forward, from the rear turret.

This is another entry into / from the aircraft. This is located on the lower portion of the rear fuselage section.

This next photo shows this location a little bit better.

This next picture I took shows how the ball turret was installed. It fed the gunner oxygen by a nearby O2 bottle.

This shows the entrance to the ball turret.

followed by another picture of the ball turret. I think the non slip flooring "could" have been added for safety reasons. I don't know if this feature was present on WW2 aircraft or not.

Here is a better close up photo I took, that shows the wooden ammunition boxes that held ammo for the waist gunners. The B-17 had a similar feature.

Look really close, and you can see the cables that are connected to the control surfaces on this next picture.

I'm ending this set of pictures with a nice picture of the Pilot's seat. Check out the "Bronze Green" color.

This one is zoomed in a little closer.

Hope these helps you.
Thanks

Thanks for sharing that printer background, Walt @luftwaffe-birdman
What an amazing pictures, Louis @lgardner. Walking through it must have already been wonderful but were you also able to have a seat in it while airborne?

Even sitting in a B-24 cockpit makes you a lucky man, my friend @lgardner!
This is an amazing pic!

Thanks Eric, @eb801, for the link I read all four of his installments, and can say my experiences are fairly similar. I purchased the Elegoo Mars 2 Pro, and their Mercury X Washing & Developing stations. My first print went well, I had issues with the Washer that did not work from the unboxing, but I have since fixed. The developer is AWESOME, and I would say a lot better than the one Michael purchased. Like him my second print which was of my 50 caliber machine gun bodies failed to print. It was due to improper setting of Home on the Z-Axis, which is critical. I would also agree it is not rocket science and someone moderately competent both mechanically and computer, would be successful. Lastly I am not shy about using what other people have done, as I don't want to set out to reinvent the wheel, but I too want to create my own files. There are plenty of free "Autocad" softwares that you can use on line, that vary in difficulty and quality. I will be using them as I am not in a position to afford an anual subscription.

I have the idea that some of these after market guys, could now just sell you the file, to use at home, and you print your own parts. I know there may be an issue of sharing the files, but I think it may be a way to easily share builds. I know I just saw Gaspatch Models has released their Me163 with and upgrade printed resin detail kit.

I will take pictures of my equipment and the Norden Bombsites I printed last night and post tonight.

I found a file for what was supposed to be a 1/16 scale Norden Bombsight. I downloaded it and looked up measurements of the bombsite on line. I loaded it into my printer program and scaled it based on it being 1/16 scale, which put the Z-axis at 11.91mm to convert it to 1/48. I printed up a batch on basic setting and they turned out pretty nice, just too big.

I had an old Monogram B-17 interior from a scrapped kit, and measured it out and determined I was probably almost 2mm too tall. I loaded up the sites again changed the Z-axis to 10mm and changed my slices from 0.05mm to 0.025mm and printed up another batch. These actually look about right, some parts smaller then the injection molding but over all length, width and height matching pretty close to the kit. The details are different but I think once painted will look pretty good. By reducing the slice thickness the detail in the smaller print was actually better.

I will be putting this in the nose compartment of my B-24.
