I have two. Thinking I'd never find one here in the island, I bought the 1948 off eBay. A year later, I saw a 1947 on Craigslist and it was only 10 minutes away sp I had to go see it and, of course, it came home with me. The 1947 was owned by a ballerina, now in her early 90's, and she used it to sew costumes. I bought it from her daughter. I love both and use them all the time. I also have a 1906 Singer treadle owned by my great grandmother.
