Looks good, Bob. I hope you'll show it to us again when it's finished! I've heard the Hawken Shop kits are among the best, with regard to authenticity. They should be commended, especially, for the barrel... Seven grooves, 1:48" twist, and tapered octagon, as much like the originals as they could get.
I like your new book, by the way. I ordered it as soon as I found out about it. It is a nice reference.
