There was a pretty nice example, full chromed, for sale on Ebay a year plus ago by a Mr. Scott, I believe, in the Midwest.. Do others recall that gentleman who occasionally has early stuff for sale?
Also I think the name has a significance that I do not know. Can one of our British members expound upon that for us?
