Bought from TL Williams back in 2015. I don't know too much about it other than it's an early version from the 40's and there are only 2 others of this type/design known to exist. Any other questions contact Terry himself.

Asking 2k. You arrange shipping or you can pick up. Located in Portland, Oregon.
