Cap for C-8   lenses. It seems to be rear cap. It is  46.5mm ID 50mm OD. Slip on type cap. 

Cap works good. It shows some wear, but it is not damaged in any way. It has some marker writing on top.  It will protect your lens from dust. I would rate it at  8  out of 10. 

Shipping is free within USA and $3  worldwide. 

Cap will be shipped just as pictured without any accessories. No other accessories will be included in this listing. We will pack it well to protect it during transportation.
