Help IDing a tool

[Mick-Boy]

A friend of the family sent me this photo and asked if I knew what this was. Her father was a Marine but she didn?t know if that was related.

I can?t shake the feeling that I?ve seen one of these before but I can?t place it. Reverse image search didn?t turn up anything. Any ideas?

Its used to polish brass buttons on a uniform. You see them for sale on Ebay. WW2.

Awesome. Thanks.

Okay, I did not see the connection to brass buttons.
A little Google search.

Yeah, you put the buttons on the uniform through the gaps in the tool so that when you polish them you do not get the fabric dirty.

That's pretty cool.

Amazing. I just learned something new.

Never shined any buttons, or boots for that matter ;)
