Good luck with TF/GP. I bought an original Elder40 that had been sitting in a hobby shop for a LONG time.
Either the wood in the kit had grown, or the plans shrunk, but there was at least a 2% difference in the parts vs plan layout.
I contacted TF, as well as Ms. Cross directly, and was informed that they did not have archived copies of the plans that they could sell.

Imagine how surprised I was last year when they reintroduced the kit.
