G'day all.
A Czek television camera collector Zdenek has successfully restored a 1965 Tesla TK-402 3" image orthicon camera to good working condition and has recently featured it on his YouTube channel. He has made the video in two parts:

Very interesting looking camera, the design of the enclosure looks loosely based off that of the RCA TK-11/31 and am surprised it was manufactured in 1965 when it looks more 1955. Anyways this camera is making brilliant 1950s style B&W 3" IO pictures and the video demonstration on this camera is fantastic!
Enjoy!
Cheers
