Thanks for all of the suggestions. I found a C700 Dichoric head, new in the box, with both the 35mm and 6x7 mixing chambers for a very reasonable price. The mounting arangement is different but, for the moment, that is not important since I already have a functioning head with C760 mountings.
My objective in buying the Omega was to have a second enlarger for medium format that I would not have to change out the lens and negatrans on my 23CIII. Until I can find some negative carriers, I will just use this one for my contact sheets.
