That remoinds me... Some time back I bought a Sony portable video 
recorder and camera. No, I don't mean a camcorder, this is 2 separate 
units powered by a lead-acid battery pack. It's not a VCR either, it 
uses reels of tape. Oh, it's monochrome only (EIAJ format on the tape, 
thankfully). Anyway, I didn't pay much for it. Only later when I took the 
bits out of the cardboard box did I find a couple of C-mount lenses in 
the bottom. Kern-Paillard Switar lenses.... :-)

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 
theads msyelf (32tpi is trivial to cut on a lathe with an 8 tpi leadscrew
