Thanks Jim, I found plenty of similar knives in my usual search places just none were Plumbs and none had the square scabbard.
The knife and scabbard are pretty much new condition sans the scuffs from the scabbard, the scabbard seems to fit perfect.
I bought it from a older fella today at a show, it is inked "good hunting" from Flick and Bub on the front, he said Flick and Bub were his uncles stationed in the Philipines and they sent it to him as a gift. He also said Flick and Bub never made it home.
