Let me start out by saying I'm not a Spitfire expert by any means. This is to allow you, (the viewer) the opportunity to see for yourself what some of the talk about Spitfires is about. Please draw your own conclusions. I'm not trying to sway your opinion one way or another. I can't vouch for the Tamiya drawings as far as accuracy. It's all I had available.
I do not know how "true" the Tamiya drawings are. They do fit the outline of the Tamiya parts perfectly however. This should be expected, since they go together. I didn't have another 1/48 scale drawing to use as a reference.
But this will be good enough to demonstrate the differences between the kits... Please keep in mind that the photography angles will distort the appearance of how far off a plastic part is when viewed from different angles. Where this occurred, I tried to take a close up photo to show exactly how far off the plastic was from the drawings.
I took pictures of the fuselage side plastic for each Spitfire (and the last 4 unbuilt kits shown above). I used a standard drawing that comes with the Tamiya kits as a camouflage painting guide as a standard reference.
Then I placed the corresponding Tamiya fuselage half over the drawing, lining it up as close as I possibly could. This is a typical photo you get. If you look close, in this picture it looks like the nose is longer than the drawing (but it is not). In fact, the Tamiya parts fit the Tamiya drawing perfectly. This illusion is in part due to the fact these Tamiya Mark 1 fuselages have been glued together. It would have been more of a true representation if the parts were still apart. The other thing that caused this is the angle of the camera when the picture was taken.
Here I took a Tamiya Spitfire Mark 1 upper wing half and placed it directly over the drawing. This picture is a much better example to go by. You can see the wing fits the outline of the drawing very well indeed.
I had three Tamiya Spitfire drawings to go by. One is for a Mark 1, next is a Mark Vb, and the last was a Mark Vb Tropical. I aligned the outlines first, then placed them up against a bright light and checked the to see how the outlines were.
The earlier Mark 1 had a different spinner, and some minor changes in the panel lines on the engine panels.
The overall dimensions looked to be very similar on the later Mark V, other than the Vokes filter.
Using this method of placing the plastic fuselage halves against the Tamiya drawing, I took some pictures of each kit represented in the build. I started with the Airfix Mk 1, and there were some minor differences...
The main thing I noticed were the length of the fuselage in the nose,
and a panel line ahead of the cockpit windscreen was way different. This is where Airfix has an insert for the different types of glass, armored or not.
Next up, I changed over to the Tamiya Mk V drawings since I was measuring a Mk V airframe...
and placed the Tamiya Mk V Tropical fuselage on top of the drawing.
Again the fit was spot on.
But then again the Tamiya drawing was used.
here's the same thing, but this time I'm measuring the Tamiya Mk Vb against the Tamiya Mk Vb drawings. The same results were achieved... I used this Mark Vb drawing for the rest of the demonstration...
Next up was the Airfix Mk Vb placed over the Tamiya drawing.
With the same results as the earlier Mark 1. The fuselage panel line was off considerably.
and the nose was approximately 3 MM longer than the Tamiya kit.
Next up, the Airfix Mk XII
There was a slight difference noted on the outline of the rudder / fin
and the nose was about 3 MM longer too, just as it was on the earlier Airfix MkVb
Then I shifted gears and measured the PR Mk XIX. This plane had a different engine than that used in the earlier Marks. I'm fairly sure these were Griffon powered, so the nose will be different.
The tail was lightly different ...
and so was the nose, which was expected due to the different engine used.
Next up, the Airfix FR 46/47, just for kicks. I didn't expect this one to fit anywhere. (and it didn't) π
Here's the nose of the FR 46/47
Here's the Special Hobby / Revell of Germany re box of the Seafire Mk XV.
This one was pretty close to the Tamiya drawing. Look at the tail outline.
The cockpit
and the nose was different, but this was expected too...
Shifting gears to the Hasegawa kits:
Here's the Mk VI
It was really close around the cockpit.
as was the general outline and location of the tail.
Quite honestly, the nose was the same length as the Tamiya version too...
The next Spitfire is the Hasegawa Mk IXc
where you can see the cockpit is very close to the same location as the Tamiya MKV.
and the outline (and location) of the tail is very close too.
There was a difference in the length of the nose however. It was approximately 3 MM longer than the Tamiya Mk V. This is due to the different engine used in the Mk IX, which was a Merlin 61.
This next photo shows a Tamiya Mk 1 on the top of the photo, and the Airfix Mk 1 on the bottom. I lined up the rudder hinge line for a comparison. Sorry the photo is a little canted...
This next picture is self explanatory. From top to bottom:
Special Hobby / Revell of Germany Mk Seafire Mk XV.
Next is the Airfix PR XIX
Last is the Airfix FR 46/47
In this next picture, you can see the following kits. from top to bottom:
Airfix Mk 1
Airfix Mk Vb
Hasegawa Mk VI
Hasegawa Mk IXc
Airfix Mk XII
Finally the Tamiya kits are on deck. Please keep in mind these have been assembled and will not lay flat on the drawing. From top to bottom:
Mk 1
Mk Vb
Mk Vb Tropical
In this last picture, I have all of the planes laid out for inspection. Sharp eyed viewers will notice that only one Tamiya Mk 1 is shown, when I'm building two...
