Wow, Thank you PeteM,
That is a huge piece of the puzzle that I didn't have before...I live in Buffalo so this is extremely helpful to my understanding of the local trade...that makes 4 gunsmith/double barrel patent holders in the Genesee and Main section of downtown Buffalo over a 75 year span....including Escherich, 2,092,850 Otto Neubrand, Emil Flues, and one other (my Western New York file is out at the moment)....plus the many gunsmiths and apprentices who weren't patent holders...
I'll be digging deeper into this Escherich damascus mystery over the next week, I'll report anything that I find...thanks again
