I'm not an antique machine collector but last week saw an old Singer in portable case for $8 at a flea market. I have an old cabinet machine that needs to go to the repair shop so I measured its base and went back to see if the carrying case would interchange with my machine to make it easier to go for repair. It was the same so I bought the Singer, brought it home and put it in my cabinet and put my machine in the carrying case. Then I got online and found out the Singer was made in 1918 and was a model 66. It was missing the slide plate over bobbin but I found that at a nearby store for $5.00. So now I have $13 invested in this machine and thanks to Billy, I see how beautiful it can be if cleaned up. I wasn't sure how to thread it but it did sew even if not threaded correctly. Just wanted to say "Thank ye, thank ye, thank ye", as Gomer Pyle used to say. I love this quilting board.
