Looks similar to a 1950's era schrade/walden H-15 but there is usually a plastic piece behind the finger guard and the pommel was silver, brushed aluminum i think. now that I think about it I dont think the finger guard extended on both sides like that one does.. But the blade shape and handle very much resembles an H15
Thanks Belt... No plastic anywhere and really doesn't look like any would be missing.
