It looks to be of similar vintage to the Singer I got in the mid 60s.
Mine worked great for many years through many air force moves. Finally damaged it myself by accidentally shoving it against a wall with the buttonhole attachment on and bent the bar that holds the needle.
Just be sure to check out the machine thoroughly before you purchase to be sure it stitches well and sounds like it has been kept well oiled.
This should be a very good machine.
