I have a 201-2, birthdate April, 1946. I have had 'her' since 1957. Here is what I have learned. Most of the FW attachments will fit the 201-2 because it is a low-shank machine. How do I know this, because I 'adopted' a 222 FW earlier this year after considerable research. My free-arm is a 1960 and all the attachments I have tried on the 222 I have tried on the 201-2. Maybe there is a 201 Fanatics group like there is for the FW's. Just start Googling for 201-2 Singer attachments. There is a website, www.singeroriginalvintageproducts.com The fellow's name is Duane. I know others will certainly repond to your questions and need. Libber
