I just brought my grandmother's Elgin Rotary Treadle machine home. The original warranty receipt is dated 15 Dec 1936. There is also some New Home paperwork in one of the drawers. It was purchased in Rockford, IL from the Elgin Sewing Machine and Bicycle Company. No one has used it for many many years, and I'm trying to get it up and running. I'm also on the front range...Parker, and would appreciate ANY assistance you might have, since you possibly have a similar treadle machine. Thank you
