Front protective cap for lens "Industar-50"
for 37mm lens front, plastic
"KMZ" plant, USSR

Very good condition. Cap has small signs of age and use.

Lens "Industar-50" is 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 silver "Industar-50" lens firmly. 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.
