Lovely, vintage (1950s/60s?) set that includes 5 optical filters in mounts (Blue, Green, Red, Yellow and Clear) + condenser lens in original Schott case

Everything looks to be in very good cosmetic condition - please see all photos

I am unable to find the exact specifications of this kit or identify exactly which microscope types it was compatible with (welcome feedback if others have more information)

The dimensions are:  Colour filter diameter around 7mm, condenser lens diameter 24mm and length of connected units 35mm.
