I got it!
The good news - it was on sale even lower than the posted price.
The bad news - that's what I got for the Melody Maker - we did a straight trade. So I basically got $700 for the MM - he said they would sell it for $1100. But all things considered, I think I made out ok! We don't call it an "evertilt" bridge for nothing!
Dug around some more - found one person claiming 400 produced, another that 150 were imported to the USA. I find the 150 a bit doubtful - mine is #153!
