WW2 - Metal Insignia
I bought these at an estate tag sale and was told the guy saw service with the PT Boats during WW2. They are marked "Vanguard, N.Y." on the reverse, but the box is to "Hilborn-Hamburger, Inc., Mfrs. Military Insignia". There were also some Chief Warrant Officers bars, some Navy ribbon bars, strap for visor cap, larger Lt. bars, buttons, etc. Take everything for $40.
