What is this #IV

[bmac]

I believe this is an adapter for either a cold light head or a minolta 45A head. It was attached to the Beseler 23C II XL I had a while ago. Can anyone confirm? IS anyone looking for one of these?

Does it have a part number or measurements?

Brian,

Looking at it and comparing it to my Cold Light Head & 45A head and 45MX Enlarger I would say the it would fit both the Cold Light or the 45A head.
