Help identifying inherited military short sword/bayonet

[ArtifactAlex]

Hello everyone,

I'm hoping someone can help identify this piece that belonged to my grandfather.

Unfortunately, I don't know its history or how he acquired it. He served in the U.S. Coast Guard, but to my knowledge he never served overseas in Korea. Because of that, I'm not assuming this piece is Korean, and I'm hoping to identify where it actually originated. so we're trying to determine whether this is military, ceremonial, foreign, or something else.


Here are the details:

• Overall length: (I'll add measurements shortly.)
• Straight, single-edged blade with a spear point.
• Black ribbed grip that appears to be molded material rather than wood.
• Plain steel guard.
• Metal scabbard with two suspension rings and decorative band.
• Decorative shell-like cap at the top of the scabbard.
• The only visible marking I've found is the number "21" stamped into the guard. I have not found any maker's marks on the blade or elsewhere.

I've attached photos of both sides of the blade, the scabbard, the guard showing the "21" stamp, and close-up photos of the fittings.

Does anyone recognize the pattern, country of origin, or approximate period? Also, does the "21" look like an assembly number, rack number, inspection mark, or something else?

Thank you for any help.

A German made 'Grecian' series fraternal and theatrical. I'll pull some books by the weekend but it likely won't be in there, just very similar to US production. There was also Francis Bannerman, a fellow that bought surplus. The grip and pommel based on these, Maybe even the blade. The scabbard though is straight costume ware and not an Ecole de Mars cadet's sword
