Seven various US Navy ratings, MOS, and years in service patches. Six are heavy white cotton, and one is dark navy-blue wool fabric. All the patches have been used. I have not tried to clean them. The two patches with the intertwined rope designate Apprentice Petty Officer 1st Class rating, and the two patches with the intertwined oblong shapes designate Electronics Technician ratings. The remaining three patches represent the years the sailor was in service. Each Hash Mark represents four years. All sold together.
