I have a spare Beseler 45 that might fit the bill. It actually has an Ilford 500 head on it, but that is being transferred to its replacement (an L1200) and the old condensor head is going back on it. There are a lot of lens boards and neg holders for it including the 35 and MF negatrans units and the 4x5 negaflat glassless holder. PM me if you are interested and I can arrange a time for you to come and have a look at it.
