Someone correct me if I'm wrong, but Postal Workers were government employees. At that time (1961) government employees did not pay into Social Security. They paid into a separate retirement plan for government employees and would have received this retirement instead of Social Security. I was a civilian employee for the Air Force at that time. I can't help you as to where to write for information as I left government employment and became self-employed and worked at home.
