Info on Vintage brass bell buckle please

Can anybody tell me about this belt buckle? It was my grandfather’s he collected a long time ago. The closest thing I’ve found out so far is it’s a brass insect face buckle.

This wouldn’t be associated with Native American jewelry, not sure if you are going to find an answer here. It is such a unique piece, might be associated with a marketing effort. It is probably one of many.

Thanks for your help

So fun!! Reminds me of the stubborn doorkonckers in the movie The Labrynth.
