1. A skilled builder made this rifle.
2. Even if unsigned, the builder's hand shows commonalities with other builders where he lived.
3. The features of this rifle are western Pennsylvania, particularly Westmoreland County.
4. Those include patchbox sideplates extending past the hinge. A hinge with 5 to 7 or 9 knuckles, maybe the end "knuckles" are caps. Similar (Jacob Sell) butt plates and similar trigger guards, many are Lebanon County, Track's #TG-K-4-B. Some have comb plates and wear plates.
5. Builders with similar rifles include at least Thomas Allison, Samuel McCosh, Elisha Pancost, David Morton, John Sherry, and George Kettering. Wigle's rifles show similarities to some of these rifles, but he was a thinking man and did things his own way.
6. I disassembled and minutely examined the only known rifle signed by him, and I see his hand in these three rifles. Especially the use of lots of "stars" or crosses.
His tombstone has his name as Jacob Wigle.
His rifle after I cleaned it up for the museum display.
His combplate. Was this a reused buttplate that had a patchbox release button previously?
His rifle on the bottom and my first copy at top.
The only rifle I know of with weeping hearts pointing both up and down.
The original lock and sideplate had been replaced. Mine was a guess at what he might have had.
His wear plate (top) was lopsided with crosses on it.
His brass work was beautiful.
His rifle at top showing toeline patchbox release (The front brass plate springs to push a rod).
Originally a flintlock, converted to caplock.
His patchbox.
I would like to see a good photo of the signature on the rifle you are posting about. Where is the patchbox release?
