Longshot, I know, but...

Apparently, in 1980, my mother had a musket made for my father. Engraved on the top of the octogonal barrel (Kentucky Rifle, near as I can tell) is "G.P. DiCesare", dated 1980. I'm uploading photos shortly, but I'm just wondering if anyone's heard of him, was his work any good, etc.

I'm hanging onto the rifle (my father recently passed); I'm just trying to document what it is.

Photos will be up as soon as they finish uploading and I can edit/clean/etc them..

You might try Track of the Wolf, I do believe they are in Elk River. They may be able to help.

Sorry to hear about your father, I too lost my father a couple years ago.
Very nice looking rifle! A nice heirloom to remember him by.

Many well versed rifle builders, I’m sure they would know. There is a rifle builders forum.
If you don’t want to join up with them, I could ask the question for you.

This sounds like it may be the guy. https://www.dignitymemorial.com/obituaries/paoli-pa/gerald-dicesare-8902145
