The most obvious question is; Had you previously contacted the kit-cutter companies? A lot of these guys keep templates and the amounts of everything on file when they cut out odd models in oneseys for people. This leaves them able to jump right in and get the next request done without too much fuss. I've talked to them before, and I've been amazed at what they had stored away. I had been giving some serious thought to building a B-25 bomber at the time, but shortly after had decided against it and made my move back down towards mostly smaller models. They could have cut me a real beauty Ziroli, not cheap, but the job they do is phenomenal. Anyway, just a thought. If you were a kit cutter, I think it would make sense to keep info like that filed away, like money in the bank.
I say, hey, if you can find one who hasn't got it, you might be able to work out something with him. I've done that with cowls before, I send them my original plasti-cowl, and they build it, make a mold, and send me a f-glass cowl back, all done and ready for primer and paint! And of course, highly unlikely as a crash by me would seem, they still stand ready to replace my cowl at a moment's notice! I'd think the cutters might at least want to borrow your complete plans so they can copy them. They could cut you wing kits or whole Wacos after that, whatever you need. By the way, I really like the 1/5-scale Waco, especially the Pica (does anybody else MAKE a 1/5th scale Waco Bipe?), and they are HARD to find these days. You don't see a lot of them at the fields, either. Pretty plane, got that Golden Age look....
