Sorry “1to1scale”, but I strongly disagree with your assessment of the GM F/L conversion. Right now, it’s the most accurate 1/32 P-40F/L available. I was in communication with Derek Bradshaw when he designed the kit and provided much of the research material. As to the rear supercharger duct being so out of shape, I know Derek had several photos and plans of an original P-40F when he designed this area. I don’t feel it is wrong at all.
I agree with you that we should see what actually turns up in the Trumpeter box before passing judgment, but photos of the sprues give us reason to be initially skeptical. My greatest concern comes from the fuselage side view, particularly in front of the cockpit. While the F’s and L’s seem similar to the Allison-powered P-40’s at first glance, they are in fact very different in almost every dimension. For instance, if you look at the contour of the top of the nose on theTrumpeter kit, it would seem that they just removed the carburetor intake and left the curve in place— when in fact it is very different. Compare this to photos of a real P-40F and then look at Tom Cleavers review of the GM conversion set in a 325th FG P-40L. Link here—
Look at the side view compared to a real P-40F/L and you will see that Derek Bradshaw got it right for the most part. You can also see why many of us are concerned about the Trumpeter kit.
I don’t know about the flaws and build issues you had with the GM conversion. Of course some filling and fitting is necessary with such a conversion. I didn’t notice the other flaws you mentioned on my two sets, but mine were from the first ones cast.
So in the end, I’ll reserve final judgment on the Trumpeter kit until it actually comes onto the market. I hope they get it right in the end. But I am not optimistic having seen the pre-production photos.
