@Smokey Plainsman ,
I can’t direct you to a proper Hawken for sale right now, I have a couple of suggestions.
One is John Bergmann of Tennessee. He is a first-rate builder and much more willing to work with the customer than some. I have two rifles and a pistol from him, all custom builds, and could not be more pleased with them. One caveat is that John will build to your request, and if you want a thoroughly authentic rifle you need to research it so you know what to ask for. If I remember correctl, the wait time was around 15-18 months. Most of that is waiting for John to complete other orders. Once he gets started on your gun, I believe he concentrates on it, and you will probably have it in your hands 4-6 weeks later.
Another suggestion would be to contact The Hawken Shop. They sell a kit, but I understand they have now lined up some builders to provide you with a finished rifle. The Hawken Shop kit is for a “classic” late S. Hawken rifle in .54 caliber. They don’t offer many options but this kit was reportedly developed to be dead-nuts authentic, down to the number of grooves and twist of the rifling. I forum member recently showed us a rifle assembled from one of these kits, I think by Michael Compton (?), and it was very well done.
I‘m sorry things haven’t worked out with Brant Selb. He has been considered one of the very best of the current Hawken builders.
Good luck!
