thanks for the question.
These Ring-Masters have spiked up and down on ebay, over the last couple of years, with the "ups" being more common than the "downs" lately.
I was fairly cconfident that I had bought a nice one on ebay, in the $150 / 200 range, and along came Jim Nichols, and took it right out of my hands, with only seconds remaining. This was a couple of years ago, though the memory of that ebay screen announcing "You Have Lost The Stinkin' Auction" remains vivid to this day.
More recently, they seem to have traded in the $200 to $300 range. Jim tells me that, under the provisions of his will, I get his -- I imagine at a "fair market" purchase price!
By the way -- it should have seven rings, but people often miss the blank one (shown in the Instruction Book, linked below).
Thanks again for your message,
Jeff
