I have a 301(Lynn) and she is a great workhorse. Right now she is in my closet waiting to meet her new neighbor a singer treadle machine (Dorothy) made in 1913 in Elizabeth N.J. She was a total mess and as soon as we finish her she will sit next to Lynn in my new sewing room when we finally move back to Pa. I also have a Singer 6233 and 9230 I use these two on a daily basis ( if I screw up a machine I'd rather it be one of these) I also have a ton of attachments that came with each machine and I too couldn't tell you what most of them are for just yet. I love them all. All I need now is the Featherweight and I'd be one happy lady.
