Thanks, Pete. I'll try to get pix but probably that'll happen only if my friend buys the gun (unlikely--he has the usual predjudices against "short shells"....). I suspect that the makers mark may be a marking on the water table and right barrel flat which he has "attempted to draw"! To me his sketch resembles nothing so much as a rectangle with a....sperm in it. Perhaps I might extrapolate that it is a rectangle with a stylized sickle in it? I'll look back at your reference to see if that rings a bell; didn't see it the first time (won't look for the other item....).
Could this be the mark of the barrel maker, or would that be on the barrels only?
