I just found the most amazing shop on eBay with steampunk jewelry findings, many of them vintage. The name of the shop is "Ferrera Unusual Art Supplies," and the link to the shop is http://stores.ebay.com/ferreraunusualartsupplies. Here's some of the great stuff I found:
This is a vintage English Bobby Whistle, and isn't it lovely? If you have to sound a shrill cry for help while walking down a dark alley, wouldn't you rather sound it in style? This one has a dual tone and is unfinished, so it can be made into a pendant.
Here's another find:
This has to be some of the coolest chain I have ever seen. Solid brass oval link chain, and vintage as well. They sell this in bulk, by the way -- you'll have to add your own clasp, et cetera.
Okay, last photo:
These would look great on a necklace. Speaking of which, this shop also has a nice collection of finished bracelets and rings. Definitely worth checking out.
Thanks, and have a great day!
