Trying to find information on my father's service records. He was a veteran of WWII. I know he was in the Army and probably an MP. I have an return address on a letter he sent to my mother. PVT. James Walden, 3004th Qm. BKY. Co. APO. 331, San Francisco, CAL. Could this be the unit or company he was in. any information will be helpful.
