I believe this turret is for an Omega D5500 enlarger, but I don't own one and have never seen one so I can't be certain. It's marked on the back (light-side)
B.T.C. 9-401-0164
and comes with two Omega lens plates, 421-932 and 421-135. The basic mounting holes in the turret are 39mm. The 421-932 is a 39mm mount with 15mm of extension, and the 421-135 is a 42mm mount also with 15mm of extension.
This is a nicely built gadget but I haven't been able to figure out an easy adaptation to my Beseler 45. It is used, but in excellent condition. $60 plus shipping in the US. I would like to sell the turret and plates together.
