Appropriate Front Lens Cap

Can anyone tell me what the appropriate front lens cap for the early Jupiter 8 would look like?

Is it just a plain silver metal cap without any engraving?

Thanks,
Steve

Hello Steve

I have some 14 Jupiter 8 here and I never seen an other lens cap than this metal cap without engraving.

Best wishes - Guido

Thank you, Guido.
I suspected that was the case. I have a number of them.

Take Care,
Steve
