Boy, that info caught my attention.
I just picked up what I thought was a 37-640MX in Southern California for 49 dollars. I just read your info about the 1937 mid-year cancellation of the 640 and it's replacement.
Looks like I do have a 640 and not a 630, gold speaker cloth and 7 tubes compared to the 6 in the 630.
Thanks for the absolute wealth of info you provide all of us!
