Beseler Mounting Collar for Aristo D2 Cold Light Heads

Aristo model D2 and D2-HI cold light heads are designed to fit in the condenser lens housing of Omega 4x5 enlargers. These heads can also be installed on Beseler 4x5 enlargers using the Beseler condenser housing or color head. If you lack the original Beseler lamphouse, or wish to be able to conveniently switch back and forth between light sources, this metal collar can be used to mount the Aristo head on the Beseler 4x5 chassis.
