P. A. Riddle Jr.; Shoulder Patches
I can furnish authentic shoulder patches at $10 each. That includes postage & handing. I can also furnish distinctive insignia (regimental crests). Prices vary but the important thing is to determine the correct unit. 20th Infantry was an element of 6th Infantry Division during the war but was relieved from assignment to the division at - or prior to - the time of the Occupation in Korea.
