BusyBtoo Thank you for the suggestion. I checked the manual, there was no copyright info. ycart posted a-lot of good info about her mother-in-law's Dressmaker Model W-60 Deluxe Cam Zig-Zag. So I'm going with a manufacture date of 1967. I just took this machine out yesterday to oil it and take it through its paces with the different cams. What a coincidence you post about it on the same day. This was my first vintage machine, many have followed me home since. When people ask how many I have, my standard answer is "I don't know how many sewing machines I have".
