I'm wondering how similar it would be to Grizzly/Jet/Enco/MSC/Others of the same time frame?
Like my '98 Birmingham, JohnnyC17 here has/had a Cantec and sent me a copy of his and it matched very well and helped me out.
Getting a bit of my Google-Fu back. Been looking at 13x40's, cause what's an extra 4" amongst friends...
Grizzlys don't appear similar,

Though there was one where the controls layout almost matched.

Check out this site:

Scroll on down the page and look for
111-3310 Enco 13 x 40 Geared-Head Gap Bed Bench Lathe
There's (3) manuals available, a quick glance and it looks very similar to the SB pictured above.
Also over on Ozark Tool they're showing a manual that from the cover picture, might be close, but it costs US$45 (ugh)
Might provide a reference point for further searching.
