Highly Mysterious Bracelet

[fashion.fashoff]

this bracelet is the most puzzling piece i have had in a long time...
it tests at 18K white gold and features a variety of designs--a horse, screws, copper bits, etc... they are all hand-riveted onto the cuff.
i have no idea where, when, or by whom this bracelet was made.
it is not marked at all.
i don't know where to start...
i had a similar piece several years ago, it had the yellow gold screw heads going all the way around but not the strange charms/shapes.
does anyone have any insight or suggestions?

It looks to me like something hand made.

I made a mixed-metal brooch in an art class in college. It was pretty – at least I thought it was – and definitely unique. I wore it off and on for years. It never occurred to me to sign it, so the back is blank. And I wonder, now, why the instructor didn't have us sign our pieces.
