Hey Andy, we went to Fredericksburg, jeez, probably 15 - 20 years ago & there was a museum on the main drag run by little old ladies & they had what I would call a "Texas Hawken", half stock, heavy barrel, underrib, etc supposidly made by the local gunsmith back in the day. The lock & barrel were store bought from up north, but it was still pretty cool. I have no idea if the museum is still there, but if it's not, mosey over & see the Admiral Nimitiz museum, it's good too.
Rgds,
John
