So what 16g guns in 1940 weighed only 6 1/4 #s? British & Spanish Game Guns? My pre-1913 LCs weigh 6# 8 oz (28" brl) and 6# 10 oz (30" brl) My 1942 M-12 weighed 6 1/2 #. Not Remington M-31s nor Parker Trojans and certainly no autoloaders of that era. Some 4 wt brl Sterlys with 26" brls come close. I can only think of the Ithaca M-37 Featherweight?
