Three Burros in Linked Pendant: Remnant of Larger Piece; Chinese?

The larger two are hollow, an' the weight seems more like brass than silver...but the color is wrong, somehow. It's sort of between yellow brass an' alpaca, an hints of an unusual alloy with a moderate silver content. Overall length is ~5"; the largest is donkey is ~2 1/4" nose to tail an' ~5/8" thick. total weight is ~33 grams. Note the differences in the the saddles an' other horse-tack. There is a mark I just found which is Asian, but these look mostly Chinese (last pic).
Your comments are most welcome...thanks for lookin'!

 

no mining equipment , so I;d say horses..

And with Chinese coin symbols and a Chinese mark a Spanish term is, let's say, unusual.

 

You may be right...Chinese horses don't look much like SW American Mustangs. I clued off the bristle-cut manes.

 

My only excuse is my SW U.S. upbringin', AJ...we knew they were donkeys, but called them burros anyway...an' yes, with rolled r's, emphasis on the second syllable!
