I was lucky enough to receive this wonderful gift over the holidays. It belonged to my wife's father and it had not been used for over 40 years. And now it's up to me to bring it back to life.
Not so easy...
During my triage I noticed that the focus wheel is nearly impossible to rotate. Moreover, rotating it only operates one of the focus arms to move the twin lens forward and backward. I did try to dismantle the housing, but I need to get at the focus wheel to see what's really happening. If anyone knows of any schematics for the Primoflex, I would love to get my hands on them.
