Help Me Identify This Bayonet

[Fixedwing]

I can find no markings on this at all. I figured with the vast knowledge base that exists here, someone will know what this is. Thanks

Looks like some version of an HK G3 or similar.

It looks a lot like a HK G3 type but the latch is different.

Thanks guys, you got me in the right direction... (found it at worldbayonetsdotcom) copied and pasted below:


This example was made by Gesellschaft für Metallverarbeitung mbH & Co. (GMS) [in English, Society for Metalworking L.L.C.]. GMS became the first successor to Carl Eickhorn Waffenfabrik AG, purchasing the Carl Eickhorn Waffenfabrik factory in 1976. GMS went bankrupt in 1981, so this example would date from that period.
GMS introduced a larger 20 mm. pommel for its G3 products. This innovation eliminated the need to install an adapter to the G3 rifle, in order to mount a bayonet. The GMS bayonet has a 12-groove black plastic grip that is more roughly-textured than the Eickhorn bayonets. The press catch is at the 4:30 position. It has a broad plain crosspiece.
