Omega 4" X 5" negative carrier for D Series Enlarger (021)

Description

This is one of the earlier variations in the design of the negative carriers, in the almost 60 years of the omega D series enlargers' production. this is the design used for most of the production years by Omega.  The production of new D series enlargers and accessories by Omega was discontinued in 2014.
Given the physics in the design of the enlarger, the white or aluminum top plate of a negative carrier is optimum.
