Joe,
The model number is 385.1233180 and the Serial No. is 22802047. The box to me looks 1970's. I could not find a date on the manual, however, there is a picture of someone in there wearing bell bottoms.
I have a Kenmore machine here that I got out of the free room at the same thrift store. I am not sure if it has a high shank or a super high shank. That one and I have not bonded yet.
Then I have a Kenmore that a lady gave me to get rid of it. It was her HS graduation gift from her parents in the 1960s and her dad made the cabinet for it.......I use that one to free motion quilt on. Just had to replace the brushes in that one because I use it so much.
