I have a couple samples of their stuff and some chinese versions all of which are made better that that was. It was NOT up to their quality level on several fronts. The clock motor driving it had a Cramer stamp on it, but I don't recall if there was a stamp on anything in the stat itself. You know me well enough, Jon, to know I'm a sloppy working perfectionist. An oxymoron but call it what it is. That, nearly 40 years later, still upsets me. If I was to find it again, I'm likely NOT mellowed enough to keep me from calling him and asking which of his mothers legs the best part of him ran down.
