Today I was determined to get what I hope is correct information on the field installed twin .030 caliber rear firing weapons for this Midway SBD. So I spent a lot of time online and searching through my books.
Here's what I found. Most of the answers were found in my book called "SBD Dauntless in Action" by Squadron. These pictures were studied and as I was on line I checked out various restored SBD's. They all seem to match.
Here's how the single rear facing .030 caliber weapon was installed on the SBD-2 and original equipment on early dash 3's.
This illustration shows how they were field modified to carry twin .030's.
Next followed by the standard installation found on late model SBD dash 3's.
This picture shows all together and a nice picture showing the rear gunners position with twin .030's.
A few pages over in the book shows this photo of a SBD during the Midway battle.
This is the same picture after I zoomed in on it. You can see the sliding doors are open.
With this information in hand, and knowing that Accurate Miniatures offered different plastic sprues for the SBD, I searched through the several AM boxing's of the SBD kits I have on hand. I found a sprue that has the proper twin .030 guns and sliding fuselage panels. These pictures shows the two different AM fuselage sprues.
This photo is zoomed in on the single .030 plastic tree. This is correct for the early dash three's prior to Midway. It also shows the earlier raised air intake that was on the top of the cowling.
and the correct twin .030 plastic tree for a Midway build... which also has the smaller air intake. It's part number #283.
In this photo you can see the difference in the rear of the fuselage where the rear cockpit has the sliding panels. This one is for the later field modified Dash 3 versions.
This is the correct fuselage I needed for the Midway SBD (to the best of my knowledge).
There's also a small difference on one of the fuselage bulk heads. This one has a more vertical shape to it and is much thinner near the pilots head rest area. I think this is where the armor plating for the pilot was mounted.
This last picture shows how much wider the panel is behind the pilots head rest and seat area. This is correct for a Midway SBD.
The last picture shows the instrument panel after it was sprayed with interior green. The clear spot in the center is where I was holding the part with tweezers. This part is molded in clear plastic.
I accidentally mixed up more Model Master "Interior Green" than I actually needed. I didn't want to waste the paint. So I sprayed it out on a very old original boxing of the Monogram TBD Devastator that I picked up at a swap meet years ago. Now I might be a biting off more than I can chew, but I may have just started another "Midway" group build...
The Monogram TBD. Now I just have to decide on what markings to use...
