Front protective cap for lens "Jupiter-8"
for 42mm lens front, metal
"KMZ" plant, USSR

Very good condition. Cap has small signs of age and use (see the photo).

Lenses "Industar-61" and "Industar-26m" are not included and shown as an example of mount.

Please note, that this cap does not have carving, spring or anything; it's fixed at the lens with friction force only. Fixation depends on cap and lens condition, sometimes a specific cap is not fixed properly at a specific lens. Offered cap is fixed at my lenses "Industar-61" and "Industar-26m" properly, and most likely will be fixed properly at any lens with proper condition of the front part.

I do not guarantee that it will be fixed properly at your lens.
Of course, this cap can be used for any lens with front 42mm: "Jupiter-3", "Jupiter-8M", "Industar-26m", "Industar-61", "Industar-61L/D" and others.
