What type of 15
I see a lot of posts saying someone has found a Singer Class 15/clone and wondered how to tell what type it is. I see 15-90, 15-91, 15-96, 15-97, 15-86, 15-87, 15-88, 15-30....etc. How do you tell do you tell the difference other than a its class 15? Also what makes the machine a "K" or any other letter?
