I went to an estate sale earlier today and found this. There arent any decals just a metal badge that says Precision Built, Made in Japan. I dont know yet if it works, I have to check the wiring first before I try it. The case also has the lid and it smells musty. The serial number is C12753. Can anyone tell me anything about it? What else do I need to check besides the wiring and oil? Where would the oil go? Regular sewing machine oil? Thanks in advance. Oh and I paid $2 for it and I also got a knock off Ott floor lamp for $3.
