I had some questions aout colors and rings and found that there were some differences in opinion and details. Elko is so far out of the way, that the strikes are probably not that well documented.

Below are two that I happened to pick up, playing in 2001.

The one on the left is a LM and copper ring. It has a frosted design

The one on the right is also LM and has a brass ring and a high shine design.

I also have a G, RAM, with frosted design and copper ring.

I hope this information is helpful for clearing up some of the Elko variations.
