how do I tell pre 1945 patches from later repros? I am a Marine fom Korea 1st mar div. 1952 1953 want to get a collection of real ones as a hobby. I am on limited income (social security) and not in good health enough to get a job. I know they stopped wearing patches by the time I volunteered(1952). Mabey you can steer me to a reputable dealer who is honest. I dont care about condition as long as they are decent. I actually like ones used better than new. Thanks for any advice. BOB SEMPER FI
