The lathe was shipped to Israel in 1965, I was told it was used in a technical school. 
Mostly came intact, however some parts were missing (mainly gears), bought replacements via eBay. 
My father and I took it apart, painted it, and still trying to figure out how to put it all back together (:
Attached the Serial Scan, and a photo of the lathe.
Please do let me know if there is anything else in the lathe that may be of interest and I'll take a picture.
