The patterns for the P-57 conventional are nearing completion. When i (RNK) bought out Frank Gortsema, the pattern he was using had a thick hood & a smoothed out KW cab......So i started over. Then life got in the way & RNK was closed, I sold it to Dave at AITM. Now i am just making patterns for AITM. So the P-57 patterns are all new, from scratch. Separate hood & cab, cut outs for dual air cleaners. Boththe early pointed grille & bumper as well as the later flat grille & bumper.
As for a donor kit, just about any conventional kit or scratch chassis will work, although the 1/24 scale Italeri chassis suits it the best.
I do have several more cab kits that were originally going to be in the RNK line, that will be done & added to the AITM line.
As for Dave casting ILLINI kits, Not at all, he does host the Illini (IRC) line thru a link on his web site.
