Goggle Unitron History Project. Just about all you ever wanted to know about Unitron is on that site. 

To the original poster, congrats on the Unitron 152. I have a 1953-54 Unitron 152. The mounts are amazing considering their age. The Astonomy Shoppe website sells a RA motor with a hand controller that is battery powered and works like a charm.
