Anyone know approxemately when the "square top" lincolns were produced
in Toronto? I say "square top" - it has rounded corners. Cables come
out left bottom corner of the front of the case, AC/DC/REverse
polarity switch top left.

You should be able to find a copy of the manual here somewhe

http://www.lincolnelectric.com/en-us...r-manuals.aspx

Then look for copyright years amongst the pages...

If you don't have any luck, post the model and serial number that's on
it and I'll see what I can find

Oh and very nice buy!
Didn't find a serial number yet but spec number is W352-3E9
