Konishiroku Lens

Konishiroku
A lens from Konishiroku Photo Industry
Apparently, it was later named HEXAR.

This was found in my grandfather's unused camera set.
I have no knowledge of lenses, so I don't know its condition, but the exterior was in good condition.

It is marked f=50mm.

I researched the details on Google Images, but please only purchase if you are knowledgeable about this item.

I was unsure of the appropriate price, so I am listing it at the price of similar items found in my search for now.

Price negotiation is welcome.
