I've just acquired a Super 7, partially disassembled, and for the life of me I can't find a serial number on it. I've read through other threads on possible locations to no avail. I've even tried scraping paint of here and there, in the hopes that it might be buried under what looks to be a repaint. No joy.
The bed casting has the raised "Made in England" and "M3" (with a "5" just above and to the right) on the back, below the gap and the headstock.
I've looked on both edges of the ways, both front and back, on the tops of the ways, on the right hand end of the casting where the leadscrew hand wheel is, on the back machined surface (where the taper attachment bolts?) and underneath the feet. The only place left to look is under the headstock mating surface. Were serial numbers ever put there?
Any help would be appreciated.
