I have recently acquired a Beseler 23 CIIIXLI enlarger with the standard condenser head. I am thinking of fitting it with a cold head. Are the Zone VI cold heads compatible with the 23 CIII? I know they're compatible with the 23 CII series, but what about the 23 CIII?
Thanks very much for your input!
As far as I know, all of the 23C series heads are interchangeable. I've got a 23C and a 23CII and they are virtually identical (other than color), and we have some 23CIIIs at work and they appear to be exactly the same as mine, although I have never compared them first hand.
