WW II Knife

USMC WW II Combat Knife. Mfg by Camillus NY. Stacked leather handle & appears to have had a blued blade. All marks are on the guard 7 I hope I was able to get marks to show. Found this knife under seat of 1950 Chev. PU I bought in 1961. Wish I had the truck too. Knife shows knicks on the blade and tip is dull. Otherwise in good cond. Thanks for looking.
