Jack,
Your lathe is a 1947, and yes a catalog model
444, would have the
code designation NAR in the serial number, that
would be a 9" model A
6 speed horizontal motor drive(HMD) bench
lathe.
I'm not sure about the 8 on the end on the number
of a 9" , on the 10" tool room lathe
the 8 in the model number Designates a toolroom
lathe, such as CL-8-xxx-x-x.
