I have a Francotte 10 Ga. Double barrel Shotgun. It is an external hammer Damascus barrel shotgun. I haven't had any luck finding information about this type of firearm. Here is what I know about it.
My dad's uncle (my great uncle I guess) bought this shotgun from Abercrombie & Fitch in the 1930's. It is my understanding that Francotte made these for Abercrombie and Fitch. My great uncle used it to hunt ducks and geese. When he died in the 1960's my dad inherited the shotgun. When my dad died in 1981 I became the owner. It is in good condition but since it is Damascus and used black powder shot shells it has some barrel pitting. I have never shot it.
It is Model 8420 the S/N indicates it was manufactured in 1933 or 1934. The S/N is stamped on the bottom rib under the forearm and on the trigger guard tang. It is marked on the top of the barrel release tang with "Francotte Brevette" stamped on the sides of a crown. The number 559 is stamped beneath the crown.
The top rib is engraved with "No. 8420 A. Francotte Paris France B. Kitteredge & Co. CIN Club Gun".
The bottom rib is marked with the S/N, and "7813 10". The bottom left barrel has "25" and the right bottom barrel has "42" marked on them. I believe this indicates the amount of â€œchokeâ€ in the barrel.
The right lock is engraved with "Paris France" and the left with "A. Francotte".
I'm curious as to how much this piece may be worth. If you have any additional information I'd like to hear from you.
