Some progress..
Its definitely a Schaublin, the build quality is amazing
Done a bit of disassembly, cleaning and a bit of old catalog reading.
Lathe looks almost exactly same as the model on the front cover of the 1952 catalog except for the tailstock.
I can find a similar looking picture in the 1948 catalog pg6 and 1952 pg13 of headstock which identifies it as No13AR. however , i managed to find a marking on the headstock that says No3. Would welcome any comments from anyone that might know better than myself.
Tailstock has a 'magic eye' which i dont see until the 1966 catalog. Tailstock I’m guessing is from the 60's. Its a bit frozen so will be putting in an oilbath overnight. Also welcome some suggestions here!!
Bed seems to be No1C , looks same as catalog from 1940's and 1952. the catalog shows the bed differently with Schaublin 102 written on left side in 1966 catalog.
After a good scrubbing i can see that the original color of the headstock and base were gray but have been painted green, this was why I made the frankenlathe comment, only that possibly it is a machine that has been rebuilt/refurbished in past with head and tail from different era's (headstock in 1966 catalog seems to have a vertical knob for securing the pin in the dividing attachment whereas mine sits on the horizontal axis).
planning on chemically removing paint on bed , next step will be some rust removal… sandblasting the cabinet and electrolysis for the bed and carriage and reconditioning the motor...
