My Father collected, repaired and built a few Muzzle Loaders back in the 1960's. He had roughly two dozen rifles of many types and sizes, all Muzzle Loaders no flint locks. We would shoot some of them for fun when I was a kid and we made pistols once from scratch. We lived close to the Log Cabin Shop in Lodi Ohio and got all of the pieces and wood from there.
Around the mid 70's he stopped collecting as he felt the prices had gone to high and he moved on to restoring Harley Davidson Motorcycles.
I have no clue how he acquired this piece. I will probably not shoot it. The pictures do not show but it is missing a sight just forward of the J HENRY mark. Otherwise it is as clean as the pics show.
If there is any further interest in this rifle pleas let me know.
