Vintage 1950s or 1960s US Air Force Full Length 100% Wool  Trench Coat or Overcoat.   In very good condition but would benefit from a trip to the dry cleaners to knock off years of dust and dirt from storage.  Wool looks good, buttons look good, pockets are whole.  Liner is good Over all in excellent condition for its age and after dry cleaning this would appear 'near mint' in my opinion.  Tag says 33S 8405-939-7889 also is stamped M4762
