A very good condition, late WW2 ‘blackened’ III pattern Fairbairn/Sykes fitting knife.
Minor wear to the finish. Plain unmarked blade, with very, very slight tip distortion. Handle/grip marked with a small letter ‘3’ to the upper portion.
Scabbard seems to have deliberately had the belt fitting cut from it, a great shame.
