Nice- later M12's had the forward set leaf spring deleted, supposed to stop the forward travel of the forearm when dis-assembly-ing the gun into the 2 component groups. The forearm shape was also a bit larger in dia. on the field guns. about 1957-58 is when WRA dropped the option of the solid rib. i have small hands, so I like the smaller diameter pre-1940 "corncob" style forearms- But any Model 12, no matter the gauge or year of mfg. is still the "Perfect Repeater".. Nice Brittany Spaniel. How does she do on doves- all those soft feathers and the warmish weather of the early part of the season-- Do you use decoys, or are you mainly pass shooting?? RWTF
