I called about a Thermogloss Ludwig Mach 5 on Kijiji a few days ago for $300. The guy was going out to supper and by the time he got home he told me someone had offered him $500. Then it popped back up at $700 on Kijiji. I was kinda ****ed and moved on. I came home with a 22" Ludwig reso head yesterday that I got for free and couldn't help thinking that the timing would have been too perfect.... Well, during the night I checked my email and he just offered them to me for $400. I'm waiting for news, fingers crossed!
As for info, what I gather is that they were made only in 1974/75, M/P/M shells, came with 5 deep Supersensitives (this one doesn't have it) and that they weren't big sellers due to either the lugs being "ahead of their time" or that they came with the SS which made them an expensive offering at the time. I'm assuming that finding a beige thermogloss bd hoop is going to be a PITA. I have a friend who builds guitars that might be finish one to match instead of playing the fleabay game.
I'd love to snag some Atlas hardware and a period-correct SS and reproduce the catalogue pic.
