Thanks all for your comments! I agree should

I think it would be a good idea to look in old newspapers although that could get very extensive.
(Dietle) Although not the same gun that you see pictured in the book of ( Gunsmiths of Bedford, Fulton, Huntingdon, and Somerset Counties) by James B. Whiskers and Larry
Yantz, you can see it a lot of similarities like the patch box, the side plate, the double set triggers, carvings architecture etc. It pretty much has Jacob Mier written all over it, as you can see on page 113
Although on this particular patch box I could not see any traces of engravings on it, I even held it in the sunlight to get better lighting, but everything looks fairly smooth in spite of all the layers of patina on it.
Here is a closer up picture of the finial, I tried to get it detailed as much as I could with the camera.
