Walton's 115
Janey, Those are deffinatly different machines than the one I was talking about. The Waltons machine was located on the landing leading up stairs. It's difficult to see but it is in a 7 drawer singer treadle cabinet. I also have a link to Judy Norton's youtube channel where she talks about the episode "The Quilting". You can see the machine behind her a she comes down stairs into the kitchen. Finally the last picture is of the 115 that I own.
