I for one, and probably many others, would LOVE go have full sized drawings of many styles of longrifles. Especially Lehighs. The problem that I see, is that most of the REAL builders, (myself NOT included), have spent countless hours designing, redesigning, drawing, cutting, redrawing, and re-cutting to come up with their designs. I'm sure that most would not be willing to share all those trade secrets. Kind of like giving away an investment that you've made for your future. "Tricks of the Trade", so to speak.
However, I would stand in line to get said drawings, even at a fee!!
I was given a full size interpretation of the H Rupp from the lock back a few years ago. I've used this to build one gun, and will use for a couple more, but there are still a lot of details that still have to be guessed at and adapted to make that work out, ( I guess that's the artistic interpretation we are supposed to possess), so a full sized set of drawings would be just incredible. Just not sure what the great builders of these guns would be willing to give, and or stop giving their hard earned details.
