Interesting.
I think it is original although unusual.
The scabbard fittings are the type that I have only seen on Heller (Balloonman) produced pieces.
Although I think it is original, without a makers mark, a "K" stamp and a DLV/NSFK stamp, hanger missing, etc. I think the market for this piece (and your opportunity to re-sell it someday) is pretty slim.
Personally... I would definately pass on this one.
Just my opinion.
Good hunting,
