My best friend is the current Joe Bogle, his 5th great grandfather made the original Bogle rifle. Joe has been a rifle builder and luthier for most of his adult life but just found out about his grandfather about 20 years ago.
He took measurements from the original Bogle rifle at the Museum of Appalachia years ago and started replicating them, he forged all of the mounts and even the lock plate, he used modern internals on his locks.
Here he is with the original rifle.
Because so many of his friends that he built rifles for didn't shoot flint he made a number of the rifles in percussion, he even gave me one.
Unfortunatelyy, Joe is 82 and battling serious prostate and bladder cancer, he is scheduled to get everything removed at Vanderbilt in the near future.
It looks like his gun building days are over.
