i dont have to many U.S blades. i thought i would share my M-3. she is not the bell of the ball, or in mint shape. it was field carried, and shows it's use. most of the grey phosphate finish is still on the blade, has some very light surface crud, it has not been cleand since it was brought home. still has dirt in the grooves on the grip.
it is made by imperial and marked on the blade. my understanding is this style was not made very long.
i also have a knuckle duster that i'm not familiar with as far as time frame of use. i'm sure its U.S but no markings on it that i can find, other than the numbers 110 stamped inside the knuckle 's. any help would be great.
thank you andrew
