I'm not sure of the maker of the knife shown in the photo posted by Steve (Holzinger258), but it looks a lot like the "Powder River Knife" I had years ago.

Eric - Your's is an original Barry Wood knife which I believe was made before he started using model numbers. It is serial numbered, which is fairly unusual and has Barry Wood's own monogram, indicating that he was the actual assembler.

The Barry Wood folders are seen in many variations. There are quite a few different ones with very low production numbers and even "one-off" knives that are unique.
