Perhaps someone could help me find information on maintenance on my Singer 66 treadle machine. I have a reproduction instruction booklet, but theere is no information on where to oil it. I bought it for the cabinet ( to make a nightstand), but when I opened it, there was the machine in pristine, but used, condition with the purchase papers and installmentpayment schedule. It is written in German(I )believe, and cost $88 in 1928. I would appreciate any help anyone can give me so I can get her in her best running condition. D.Stair
