Identifying Zone VI Cold Light Heads

[pjimas]

I have a few Zone VI Cold Light Heads, how do you know which enlargers they fit?
Thanks,
Jim:rolleyes:

Jim,

The Beseler and Omega were the same head, but each needed a ring or an adapter to fit the enlarger.

What are the measures of the units you have?

Allen,

The bottom dimension where lamp is is 6.5 inches diameter
The height is 5 inches
The top is 5 7/8 inches diameter

0ne has a white diffuser that fits over the bottom with a mounting ring.

I bought them a few years ago, I think they fit a Beseler 4x5

It appears all three units are the same.
Thanks,
Jim
