My L.C. Smith Field Grade Featherweight 12 was made in 1941. Its 30" M&F barrels have the Ordnance stamp in addition to the usual marks, presumably from the Rochester NY arsenal. What's interesting is that there's another set of 26" barrels with open chokes and its own forend, numbered to the gun. The style of matting on the ribs is different on each set, so my assumption is that the gun went back to the factory after the war for the shorter barrels. Condition is excellent, including bores. I can't shoot it nearly as well as my Lefever I grade though -- stock dimensions do make a difference.
