Western Field was a brand name used by Montgomery Ward department store. he guns were made by many different manufacturers. The Wards Mod.30-SB562A is actually a Stevens 520. This is the "A" style receiver with different tang lengths than original 520 model. A replacement barrel for the 520 will not fit properly the 520"A" receiver because threaded end is shorter.
I'm assuming the Trench, Riot, and Training versions all had the same magazine. If this is correct, my 520-30 holds 5 in the magazine + 1 in the chamber.
