Since the Ju-88 group build looks like one that I have no chance of finishing in time, I would like to enter this one, if I may.
I will build the Toko P-63A kit. Luckily, it includes the ventral fin for the P-63C-5. I will decide what to do about the canopy in due course. It's not as awful as one or two reviews make it out to be, but it may need a little grinding and polishing to deal with a bit of distortion or misplaced canopy frame. Need to examine photos.
I have to use some imagination about the markings. While it is easy enough to see which planes went to the VVS (see Joe Baugher's online lists of airframe serial numbers of US planes), it is not easy to find photos of Soviet P-63s of 17 IAP and 821 IAP of 190 IAD; 781 IAP and 940 IAP of 245 IAD; or 888 IAP and 410 ShAP of 128 SAD. These are the units that were arrayed against the Japanese in August 1945 that had P-63s. It looks as if I will need to buy some decals for the tail number, which will begin either "311..." or "444...".
I'm not sure I can devote the time needed for a model right now, but here goes.
