Anything that looks like that around the area of Herrnhut?
It looks to me like a representation of a hallowed location or an estate, with musicians taking the place of angels or cherubs.
Frankly, I don't think it's really productive to try to find an exact location that matches up with the image as per a photograph, as - much like the rest of the furniture engraving - it's likely meant to be viewed in the abstract or merely representative.
Meanwhile, we still have a boldly engraved name upon the lock: J. Heinerrich Fessler.
One "Henrich Fesler" arrived in 1733 and a "Johan Heinrich Fessler" in 1766. Both are reasonable targets, the first especially so.
Henrich Fessler arrived on the Samuel, was 50 years old with a 48 year old wife Maria and a 22 year old daughter Maria. I can't immediately find out anything else about him.
Dave Madary sent me some information a while back regarding a Johan Henrich Fesler who was specifically noted as a "Buchsenmacher" in a 1712 court action in Wertheim.
Could these two be the same guy? 50 years old in 1733 means a birth in 1683, so he would be certainly old enough to be noted as gunmaker in 1712. ***IF*** both were the same guy, the two really interesting questions then would be (1) how long did he live after 1733, and (2) just how early could this rifle be dated?
Let's say it was the same guy and he worked 10 years after arrival. Could this rifle date to 1743? Can were compare it to dated or similar German examples to decide?
The questions sure keep a'rollin.
