As the seller told it is a Focomat Ic but after reading manual, Focomat Ic have tilt heads but mine does not have one.
Also on the enlarger head it is only written as Leitz Wetzlar Germany and no mentioning about Focomat Ic or any other model, but it has Focotar 50mm f/4.5 DOOCQ and a 75W lamp attached to it.
I will replace the cable and the plug, since old German plug does not fit into the new ones. May be I will rewire it to by-pass the old switch attached to it.
I had a lC once upon a time 30 years ago. It didn't have a tilt head either.
There were several incarnations of this model. This looks early, the next version had a filter drawer in the lamp housing. Later they went to a lighter finish and taller column(memory)
Does the Leica site have any information on it?
