I have such a machine as in the attached picture. GIETZ production date around 1960. I have to renew the inking rollers. Can someone has a similar and could give me what should be the proper diameter of the rolls, or where I could find such data. Maybe someone has an old manual for this machine. I will be grateful for your help.

You could try asking Justin Knopp at Typoretum, Ed Denovan at Hellbox Letter Foundry or Studio on Fire — those are the only three that I know of that have a press the same/similar to the one you do.
As the press has adjustable rails, the diameter of the form rollers should be identical with the diameter of the trucks/runners. Nice press.
Thank you for your help
I have one more question.
What should be the proper hardness of rubber on the inking rollers. These old have a hardness of 40 Shore. I read that should be 20-25
Thank you and best regards
