Second pattern snail drum with two concentric rings on the "underside" and one on top with the folding winding lever. Both sides are marked with the makers' code, "B/N" (Gebruder Bing, Nurnberg), and the serial number, "670518". A "Crown/S" proof mark is stamped on the upper left side of the magazine column. The numbers "12", "17", "22", "27" and "32" are stamped around the circumference on one side.

Arsenal refurbished, with some mild spotting and extensive pitting, along with the balance retaining strong original blue color. Spring is strong.
