Any one know maker, an how old?

Looks they might be old, no idea of maker or time frame, they're totally different than any brass knuckles on google images.

Looks like the knuckles to a ww1 trench knife. Is there a place where a knife blade was broken off?

Don't know but Congrats on a cool find.

 

[Gunrunner61]

cool find for sure..............HH

It appears you have them on upsidedown. The bigger hole should be for index finger - right ?

That's what I thought at first about the WW I trench knife, it all looks like one piece. No knife hole. It is now a paper weight. Here in Texas it is illegal to posses (if you have'em on you) brass knuckles. Cool conversation piece though. Thanks folks!
