As of coures are body caps..
The only problem was, I didn't have an C
mount lens caps. And they seem
to be very hard to get. In the end, I bought some brass rod and cut the

:-)).
If you are looking for C-mount rear lens caps, they are,
indeed hard to find. BUT, eBay has a lot of cheap 5mm C-mount extension
tubes
("C-mount to CS-mount adapter") Put a 1" diameter thin disk
(such as, or thinner than, a USA quarter) into one of the
extension tubes, and you have a C-mount rear lens cap,
or C-mount body cap
Neat... Probably whicher and cheaper than buying a length of 1.25" brass
rod, turning it to size, cutting yhe threads, etc. But not as much fun...
