Thanks for the history, and I can solve the mystery...I got the riser from Phil in an e8ay auction...with no limbs. In a discussion with Tom, I learned that he had the other one. Comes out that he paid less for his with a set of limbs that I paid for the riser only. He sent me a picture of his and it is the twin of mine.
According to Tom, both these risers were found in Jim's shop after his death in a boating accident. You never know if you are getting the right story, but that is the one I got.
You are correct. Tom retired in Colorado and moved to East Washington State where he would be about half way between one of his kids in Washington, and one in Idaho. I lost touch with him years ago.
