I have a 1967 Dressmaker W-60 that looks like yours
I have my mother-in-law's Dressmaker Model W-60 Deluxe Cam Zig-Zag. It was shipped April 5, 1967 from City Sewing Machine Company, 818 Broadway, Marysville, Kansas 66508 Phone HI 3-3731 Owner Lee Dam. The letter said it should arrive in about 5 days.
She filled out the "SMART MONEY" PUZZLW Entry Form postcard postmarked February 2, 1967. She had to unscramble 15 Sewing related words. The letter said there were 2 1st prize winners - Mrs. Norman J. Miller, Route 2, Elberfeld, Indiana 47613 and Mrs. E. Jane Smith, 67 B Campstool Route, Cheyenne, Wyoming 82001. My mother-in-law was chosen as a 2nd prize of a $150.00 Discount Certificate. Regular Price $219.50 less Discount Check $150.00 Total Cost $69.50. I don't have the Discount Certificate but it noted an expiration date and if she was unable to use it she may assign it to a friend.
The letter states Dressmaker sewing machines are sold and serviced in all 50 states and have a 30 year guarantee bond. The bond also states the motor and electrical accessories are warranted free from defects in material and workmanship for 5 years. They also offered a Lay-Away Plan of $10.00 a month with no interest or carrying charges added.
