I had a South Bend "Heavy Ten" for 45 or more years, I think the Boxfords are a very near copy. Not sure about the 13 as I have not seen one but would guess more of the same maybe beefed up a bit. Let us know when you go to see it and maybe post a picture. My South Bend was a capable lathe I just outgrew it and being 1942 vintage was well worn.
