Once again, I was notified I won this practice bomb. It will take a few weeks to arrive , this is the only picture I have. It was advertised as a "WW2 era practice bomb", no lettering, " 91 inches long", was probably blue at one time. I believe it to be of 60's, 70's era 500 pounder? My internet search led no where as to a positive ID. Can any bomb experts ID it?
