Some type of press maybe?

Need help identifying

Stapler?  Embosser?  Office or printing related, I think.  When you push the handle down, what happens?

A pen comes down first then a square block

It maybe a antique rivot setter of some sort. If I put a piece of paper under it it punches a hole in it.

Rivets are round so not likely for rivets.
Is the ram flat on the bottom?

Maybe it is a hole punch for paper.  Notice that there is a "rule" on the side of the piece to gauge depth of hole location.  Does it punch a round or square hole in the paper?

[Binkystyle]

It punches a round hole and yes the ram is flat

Here are better pictures

There is a nipple on the bottom part

If not for paper, then for leather?

Eyelet setter ? Could be used for paper? I believe Bates made an eyelet setter for paper. Regards, Lou

To me it looks like paper or leather as the others have said.I've had a few brake rivet tools (still have 2 Barretts) They are pretty stout and do brass hollow rivets for brake shoes back when those shoes were mostly asbestos.

looks like it's depressed in a ring around that bottom nipple.   my guess would be a grommet setter.   middle round piece makes sure it's centered and the square piece flattens the rest into order.   i'm also guessing that the square piece has a similar rounded depression built into it.

Hello, P_toad. I think we are all saying the same thing.This is from a google search; "An eyelet is a small piece of metal that is used to reinforce a hole in a piece of fabric; usually made of brass. ... Grommets are very similar to eyelets, because they are used to reinforce a hole as well; however, grommets are typically used for more heavy duty material than eyelets." Regards, Lou

I believe it is some sort of eyelet/grommet setter I'll have to try and find some to see if it works,it just looked like overkill to be a hole punch but you never know
