I have an assortment of C-mount / Video camera mount reducers and extenders. I used these with Mallincam cameras and G-Star cameras.
Have a look at the Mallincam website for details- https://www.mallincam.net/optical-accessories.html
I can’t remember what each one is anymore some of these were over $100 each.
The lot for $100 Posted
PM me if you are interested
