Question regarding fxo marked magazine.

[G.T.]

Hi Tac, The information Frank has given you is right as rain! When they brought black plastic bottoms on line to replace the aluminum, and also decided to delete the serial numbers... I'm sure they had an abundance of both types, and consiquently a mixture of both types... I find the mag's like the one you pictured to be one of the most interesting mags of the period..mid to late war... Best to you, til...lat'r....GT BTW, Hi Frank!
