Went to an estate sale last week, found a singer treadle machine in the garage, for 75.00 being the first day they wouldn't come down on the price, next day was going to be priced at 58.00, had to work so I put a bid in for the machine for 60.00 that way I still had a chance to get the sewing machine. They called me late on Sunday, and I picked her up on Monday night.Three manuels were in the drawers, the last page had the replacement parts prices. Needles three for 5cents mailing 1cent, bobbins 5cents mail 1cent feed dogs and presser foot, 25cent, Can't wait to clean her up, Cabinet in great shape, only two places need sanded, but they add character. Number on the machine is AC577805 the number on the manuels say 27-4, will post picture when my son comes out next so he can do it for me.
