 From other data I see on your web site, I guess this unit is a 1940 
model.  It is a bench mount, in very good condition, except for being 
very dirty and dried out (been in storage for over 25 years). I have no 
knowledge of its provenance - I bought it from a guy who has had it for 
a long time, but is moving to a new shop and was leaving some old 
equipment behind.  I have no idea who the original owner might have been.
