It is on eBay as a 'Vintage BESELER 23C Universal Colorhead Darkroom ENLARGER Lens'
It MAY be misdescribed
The Beseler CB7 4X5 head and condensers are bigger than a MX 4x5 and don't interchange easily
Ask for exact XY measurement of bottom and condensers

It looks like my mx head except mine says MX on the drawer
I will remove my head take pics and measure in 2 hours
and post

IMHO it is a 4X5 CB 7 Condenser head which is now rare
It will not fit a Beseler MX as 45 MX has a smaller diameter hole, as I gave away my MX to a member here I cannot measure a MX
Perhaps that member or another will measure their MX
All of these Beseler Condenser heads require 2 good concave face to face glass lenses to work properly
Notice the distorian in the image, that is normal
Ask if the head has condenser lenses in perfect condition, they are fragile
Lastly, I bought my CB7 head as NOS from a member here and I have 2 non condenser heads for my 2 CB 7 chassis, 1 is for spare parts. A working CB7 has power elevation and power focus and can be operated from a wheelchair
Good luck

I cannot measure my MCRX directly because I'm in a different location but I do have some notes that indicate the MCRX head was about 15 inches( 38cm)tall and the condensers were 6 1/4 inches or 15.9 cm in diameter. To my mind the picture of the CB7 head Tin Can illustrated does not resemble the the original posted photo. Further research may be indicated.
My head is off so I can easily measure it. But its upstairs and my back is also off so I can barely move, so it may be a few hours before I drag myself back upstairs with a ruler
Here is the manual for the MXT: http://www.jollinger.com/photo/cam-c...eler_45mxt.pdf
In the parts list it says the upper condenser is 7 1/8 in(18.1cm) diameter and lower condenser is 7 3/8 inches(18.7cm). So it appears the MCRX and the MXT do differ in the condenser measurements at least. Hope that helps.
