Ricki-
I am already in process of reproducing the 1917A1 ladder and other related parts. It is not going to be ready before end of summer and I can't promise it for sure by then, but soon after at most. Sorry I can't lend out an original, and I do not know if anyone has drawings. Mine will be exact in every detail and equal to or better than the original. If you want to make your own, I wish you the best. These things are totally cool!
