One of the most commonly broken parts on 23C II enlargers is the original crank handle. This replacement is a later design that has a couple of reinforcing ribs on the back and is less likely to break. In addition to the 23CII & 23CIII, this handle is also a replacement for other Beseler enlargers that use the same chassis, such as the 67CS2, 67SC, 67SD, etc., and the CS-20 copystand.
Note: This crank handle is NOT suitable for older 23C enlargers which used a set screw to secure the handle - please refer to the separate listing for the crank handle for earlier 23C enlargers.
