Hello all. I am new to this site and was recommended to come here with my question. My father recently passed away and I found this shotgun. I think it's a 16 gauge and on the side it says "A Francotte Maker & Patentee London." Across the top it says "Von Lengerke & Detmold New York U.S. Agents." It is serial # 20169. It looks like it was very nice at one point but it has a lot of wear. I have found a little about the maker but not whole lot. Another thing I was curious about, was this made in Belgium, went to London, and then came to New York? The triggers don't work, someone used a nail to act as a pin, and it's missing at least one more pin. I didn't take it too far apart for fear I would be unable to get it back together. I took pictures of everything I thought would help. Let me know if more pictures are needed. I'm looking for any info: year made, model, value as it sits, worth having restored, etc. Thank you all in advance!
