10th Cav Reg, Buffalo Soldiers, "Ready and Forward", early pre WW1 DUI made by A. H. Dondero, Inc. I found it in a box of modern Boy Scout pins. They come in matched pairs of left and right facing buffaloes.

 

Am guessing there is a typo about this being a pre WW 1 DI in your original post.

 

The design was approved 14 Sept 23. Nice find, too bad pin is GOA.

Dave, I have seen these referred to as pre-prong back. Is that the proper term?

Looks like a PB w/ the pin missing. There are only a couple of DIs w/ prongs, one being the 473rd IR.

Yes it was a typo and should have read pre WWII. It is a screw back with a short pin at the top. It is there only bent a little downward.

 

Better go see my optometrist.....

Here's a nice Meyer marked piece I just put on eBay for reference.
