I think my memory may be going downhill. I just found a thread on VSS from Jan. 2016, where I found the manual. I had my feathers in a snit because when Tia's ask for all my personal info to buy a download paid by paypal, so I didn't buy it.
Some more badges for this machine are Keystone AZ-5, Universal AZ-5 and Standard Sewing Super ZigZag.
Thanks, Cari. I didn't want to measure it again. I first measured where the motor was sitting, not at the outermost position. I guess I will get that done now.
