opus66,
I have to go to EDIT to see the photos. One of the problems with tapatalk is that Nelson can usually get them working again. But then in a week or two, tapatalk makes another change and they quit working again. I can fix them so that everyone sees them but it takes about 20 minutes per photo, so I had to quit doing that.
Anyway, back to your original question. The machine appears to be a mix of parts off of various models and some shop made parts.
The head stock is off of a 1/2" bed 12" Atlas or Craftsman. I think the earlier one made between 1958 and 1967, although the knobs on the QCGB selectors and on the tumbler appear to be from the later one. If the lead screw were present, I could say for sure. But the gearbox on the later one had a shaft sticking out the right end and this one appears to have a hole for the lead screw. It is missing the belt cover. And the gear cover on the left end is home made. The knob on the back gear selector is not original. The original was spherical and black.
The countershaft assembly is probably off of a 10" as I see a grease cup on the right end instead of a Gits oiler in the middle.
The bed ways look like 3/8" instead of 1/2". The nameplate photo is too out-of-focus to be able to read it or I could read the model number and say for certain.
The carriage is off of a 10" or an early 3/8" bed 12". Probably a 10" since the bed has an Atlas nameplate and the carriage probably matches the bed. So the model number may ID the donor.
The compound slide is definitely shop made. On all of the Atlas originals the machined area where the tool post sits sticks up above the rest of the casting either a little bit or a lot. The corners on the originals are all rounded. And it is much taller than the factory slides. Plus I can just make out six counter-bored holes, three front and three rear, with probably socket head cap screws in them.
There is no photo of the tailstock, so no clue there.
The floor stand is consistent with the bed being off of a 10".
