I have a lubitel with a broken diaphragm, however I am stuck about how to get to it.
The aperture blades have dislodged, and I can see there is a plastic(?) retaining ring from the film side that seems to be glued.
I am a bit apprehensive about trying to use solvent there.
Has anyone got experience with getting to the aperture blades? The Lubitel seems to be fairly disassembly unfriendly.
Once I fix it up I'll give to a digi-friend to try her hand with film. Hopefully another convert.
