Featured Neiger brothers brooch?

It is a nice brooch, but I am not seeing Neiger. Not your usual other Bohemian/Czech either.
What does the back look like?

 

Not sure yet, it’s in the mail

 

We shall see when it gets here. No Neiger "stank" on it for me either, although we Murricans usually only get some by mistake.

 

Well, here it is. I was disappointed when I flipped it over and realized it’s pin was missing. I went back and checked the listing (over 30 pieces in the lot) and sure enough, zooming in on one of the photos reveals a missing pin. no markings.

 

lower right between the two openings.... may be something?

 

Yes, I thought there does appear to be something there, but it just doesn’t seem to be anything. I’ll post a closeup

 

interesting , now they look like tool marks...

 

Pretty, but not Bohemian imo. Probably US made.
You can harvest a pin from a broken brooch, the hinge construction is quite simple.
