Part number I'd for possible replacement. Olympus bx41

[PassengerIRL]

Back after a long absence. I recently became the owner of a olympus bx41 with a phase contrast condenser. I'm currently restoring it. Some parts were missing like the lamp house. Please pardon my terminology if I'm incorrect but I'm trying to replace the lense in the illuminator as it is scratched. Would anyone know the correct name or part number.



Thanks in advance
Aaron.

That is the field lens. Does the scratch visibly affect performance?

As it looks a lot like the one used on a BH2.
I may have a spare one (have to check - currently on holiday)
Mainland Europe.

Measure it up and reach out via PM if interested.
