MIR-24 rear lens (or group), or entire damaged donor lens

[bghomofaber]

I need a spare to replace a lightly scratched rear lens for a MIR-24 (N or H is the same).

It's the one with the flat surface facing the observer watching the rear of the lens.

If it comes from a heavily damaged or filled with fungi lens it doesn't matter, what matters is that it be a not scratched one.

Mine is an MC version the acronym MC is written in white and lowercase, if this matters, so preferably a lens or group coming from an MC or mc specimen.

A non dismantled but damaged donor is not a problem I can obviously dismantle it myself.
