Matt,glad to see you got her to France in one piece.
The joints are often hard to detect because they were often filled or filleted over with foundry filler/linseed whiting potions to prevent any coolant from creeping in between the joint faces.....OZ.

Hi Matt,
Yep - I only wanted the gears, but it was easier for the seller to just take the headstock off & send that. I also got a replacement tailstock (I need to re-make the brass insert in mine, there's about 1/3" of backlash, but as I haven't (yet) found a suitable left-hand ACME tap, and my attempts at making a single-point tap have, so far, been laughable... I figured it might be quicker just to buy another one!
The lathe in question was being scrapped, I can't remember why, IIRC the screwcutting gearbox was smashed and possibly there was damage to the bed, hence it being sold for parts.

Well, I've tried my best to decipher the screw cutting dial plate, but it's just too far gone :(
I'll stick a picture on the web somewhere later (it's 11MB, too big to upload here, and I've temporarily forgotten the password to my web space...)
I can just about decipher the bottom two lines, which read:
"For any odd Whitworth pitches and all metric threads keep ???"
"screw nut engaged and return saddle by reversing feed clutch"
I'm not sure what they mean by "reversing feed clutch", as far as I know there is no such clutch. There's a forward/reverse gear, but I wouldn't want to try to use that while the lathe is in motion.
(edit: Attached a 1/2 size picture, it's still pretty big)

screw nut engaged and return saddle by reversing feed clutch.

Thanks Steve, that looks like a really good start to deciphering the plate!
Adev thank you for posting the pic of the plate! The last two lines I could read from my plate, it means, stop the lathe when the carriage arrives at the end of the thread without disengaging the half nuts, reverse the feed or the drive, and power feed the carriage back to the beginning of the cut.
thanks again, Matthew
