That's cool . If it's original military it should have an inspectors cartouche stamped on it somewhere . The markings can go un noticed unless you really look for them .I was wondering if anyone can help identify it.
Here's a couple Bayonets that I have .
Japanese Arisaka , and a spike bayo off my Lee Enfield
Stamp on the Arisaka bayo .
The British spike is a letter and number .
Check that one out real good and see what You can find .
