Wheeler and Wilson factory in New York. The serial number is underneath the bed. Tilt it back and look underneath on the left side. Go to ISMACS, look up the number and you'll know much more. 1957 sounds about right. I've only ever seen the handle on the earlier ones.
You don't have to use a 206x13 if you modify the bobbin case. Google "modify 319 bobbin case".
