Please help identify this bayonet

[A34]

Hey guys, would appreciate some help in identifying this bayonet. I need to get a set of grip screws for it. Any suggestions on where to get them? In one of the pics, you can see, I tried to use a K98 grip screw set and the nut is slightly larger than the opening.

I think it might be a Spanish Mauser bayonet, but not sure. Someone suggested maybe it's a FN M1924. Any ideas?? Thanks!

Looks a lot like a Brazilian Mauser bayonet to me

Thanks. Any idea where to get grip screws?

If you don't have access to a lathe you could file the side of the K98 nut down to fit the hole. Just work slowly and carefully and file a little bit of metal off all the way round the nut.

If you don't have access to a lathe

You can always use the poor man's lathe, chuck the screw up in a drill press and use a file to reduce it while it turns.

Don't even need a drill press. Hand drill is all you need, almost everyone has one of those. Just be careful not to compress the threads in the chuck.

Thanks guys, that's what I'm thinking of doing. Put the nut on the screw and slowly turn it against some sandpaper to take just enough off to fit. I have some gun blue for the bare metal afterwards. It should work as an interim fix.

Yes agreed...and use a stone or file laid flat.

You'll probably find that you need to start off with a file before finishing off with emery paper. If you can find yourself a spare screw that has the correct thread on, if one first removes the head, one then has the ideal tool/device for her holding the nut in the chuck.

Thanks for the advice guys, that worked pretty well. The grip hole is countersunk, so the nut only goes down so far. Any suggestions on a poor man's way to countersink the nut to fit better? Currently it sticks out some, which i can live with, but would like a flush fit. Of course, finding the correct screw/nut set would be even better!
