Here's some more pics.
All the numbers on the bayonet match , but the scabbard does not. It is a different serial number but is stamped with the same year '38. The blade does not look like it has been sharpened (to me) and there are only a few wear marks where it goes into the scabbard.
The frog has some stampings on the back and one of them is '38 as well.
Any ideas on a ballpark $$ value ?
