John Jacob??? A brother to Henry Sr. or no relation at all??
I agree there those low sights and the barrel heating up.
I do not believe that John Sheets and his son Henry Sheets from Augusta County were in any way related to the Sheetz family of gunmakers from Shepherdstown & Charles Town.( about half of these migrated to Hampshire County)
As to the 1.Henry Sheetz Brother to Philip.( Philip was the father of John Jacob the maker of this rifle). This Henry had a son 2.Henry ( he came to Hampshire County).
Then there is 3. Henry Sheets from Augusta County son of John.
Then there is a 4.Henry Sheets gunsmith in Ohio.
Not to mention the 5.Henry Sheets gunsmith in Daviess County Missouri , who had a son John, "Captain John W. Sheets" who was shot and killed by Jesse James in a 1869 Bank Robbery. ( or is this Henry , John Sheets' son from Augusta County? You can't find Henry after 1830 or 1840 In Augusta County
Maybe he went to MO.
How can a collector ever keep it straight.
Here is a nice Frederick Sheetz rifle. Frederick was first cousin to John Jacob. I was fortunate to receive these pictures from a collector a few days back.
