Front protective cap for lens "Jupiter-8M" and "Helios-103"
for 42mm lens front, plastic
"Arsenal" plant, USSR

Very good condition. Cap has small signs of age and use.
Lenses "Jupiter-8m" and "Helios-103" 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 lens "Helios-103" 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.
