I have up for auction a vintage shaving mug and shaving brush. On the bottom of the shaving mug reads: McMICOL CHINA CLARKSBURG, W.VA. U.S.Q.M.C. ER W 431 QM-CCC MARCH 31, 1936. I won it at an auction and I believe it is used by someone in the marines. I am not exactly sure what each inital stands for but I think it is U.S. Quarter Marine corps. and Quarter Master or something like that. I really am not sure but maybe someone out t knows what it stands for. This mug is 71 years old and in really good condition inside and outside. The mug measures 3" tall. I don't know if it was used by I assume that it must have been at one time. If you have any questions, please email before placing a bid thanks and happy bidding!
