where to get a thumb ring?

[Angaria]

I'm looking for someone who makes sized thumb rings to go along with my new Mongolian, but they're proving hard to find. Anyone know a good source? Thanks.

These sites list thumbrings.

Does a right handed shooter rest the arrow on the right side of a horsebow?
