Hi, I just uncovered the family lathe after many years of rare use.
In researching it, I found your s/n list.
It is nice to know someone out there keeps track of these old machines. 
I remember my dad buying it used from some old machine shop in New Haven CT around 1970.
It is a 9 inch, 3 foot bed with leather belt drive and an electric motor
hanging off the back side.  It still runs well and has a power feed
and additional gear sets for thread cutting.
It is called into use on rare occasions, to rework a car ,
boat or motorcycle part and although under powered, it gets the job done!
