? ID of two lens groups

[Greg]

In doing spring cleaning came across these two lenses. Both marked "LENS - JAPAN". Serial numbers are 561823 on the larger one and 531145 on the smaller one. Both fit directly into a Copal 0 shutter. Put both in a Copal 0 shutter and the projected image terrible. Educated guess is that they are both rear elements. Any ideas out there?
thanks

These are rear elements of the later Fujinon lenses with outside writing. It's hard to be sure, but I guess the larger one is for a 90, 105 or 120mm lens and the smaller one for a 125, 135 or 150mm lens.

If they are Fujinon lenses, measure the rear OD and cross-check from these brochures:
