Vintage / antique rolled gold snake serpent bracelet bangle, double coiled, beautiful detail

Beautiful vintage / antique rolled gold snake bangle with a double coiled design. 

This is a good quality piece, on which I was surprised to find no maker's signature - often similar pieces were made in Germany in the early 20th century, either Edwardian or Art Deco. I have recently sold an identical piece here:

And here is another example: https://www.rubylane.com/item/346207-RL1963/Art-Deco-Rolled-Gold-Flex78ible-Snake

The bracelet / bangle has a small amount of flexibility and so can eased over the hand and onto the wrist. It is quite a generous size once on.

It is in very good vintage condition - there is only minor rubbing to the rolled gold, please examine all photos and close-ups to get a good idea of this.
