Thanks= Re-Up- forgot the offset marks on a factory ribbed gun- two of my 5 pre-1950 M12's have the factory solid rib, and the 1948 Pigeon Trap has the "Old Milled Rib" with the sandblast bulled top and the "Duck-Billed" rib extension. Another sign of an after factory rib were the numer of 30" Full field guns later ribbed either with Simmons or MoneyMaker ventilated ribs, but the top milled groove in the receiver was a dead-give-away as to that, and when the Model 12 ruled the ATA roost, I am sure many "newbies" bought those modified and restocked field guns and thought - "Wow- now I have a Model 12 Trap gun- look out Vandalia, here I come"--I have several post 1935 12 gauge Model 12 buttstocks and also 18 ring forearms in my "parts boxes, also older logo and non-logo repro 12 gauge black bakelite buttplates-the 16 and 20 and 28- all on the same size receiver, take the same stock configuration.
