Computar 4MM TV lens 1:1.2 made in Japan and similar items

This is a Computar 4mm 1:1.2 TV lens, unused and in brand new condition, never been unpacked before, but it is older stock. I'm not sure of the age; my father used to work for Diebold (retired about ten years ago) and it was among his things, and it's made in Japan, which makes me think it's a couple of decades old. I could be wrong though; I don't know much about these things. If you have any questions, please feel free to ask and I'll answer to the best of my ability. Asking $5.00 obo. Everything I have listed for sale is "or best offer", so feel free to make an offer. ~~~~~ ALL ITEMS ARE AVAILABLE FOR LOCAL PICKUP. I sell a huge variety of stuff to supplement my income and help me put the last of my kids through college. Some items come from flea markets or estate sales, and some come from around our home, but many items come to me from my extended family of hardcore hoarders. So, the variety really can be vast and unpredictable. Please check back often, because you really never know what I will have from one day to the next! Thanks for visiting and have a great day!
