My father handed me down an old 16 guage doublegun and need a little info on. I know there has been some discussion on this, but the gun reads under the barrels:
St. Etienne / ECTIFIL C.A./ 17.1 / 3623
There was some other distinct markings in the same area, but I would have to look at them again to explain them. I would like to find out about how old it is, what is a safe load to use and where I might find parts if I was to ever need them. the gun is in good working order and I would call it good to fair condition.
