Many Winchester Mod. 12 have been modified by "Simmons" in USA to fake a real Mod. 12 Trap Gun.
Not all M12 Trap guns were marked with the "trap" designation bottom side of the reciever/mag tube. The last ones made were not for some reason...cost cutting maybe? My 1948 trap gun is but the 1963 trap I have recently aquired is not.
It is a factory trap model, duck bill ramp, three pin rib, off set proof and factory red recoil pad. The lumber is outstanding and straight stock as opposed to the monte carlo which was also offered.
More of a bridge than a rib. Certainly not a fake as it doesnt look anything like the OEM rib.
