Marconi B3200 colour television camera
(early cameras had the BD848 number from the previous model)
This is the third and last of Marconi's Image Orthicon cameras. It was a really big camera with three 3 inch Image Orthicon tubes in it. Soon after this was designed Philips invented the Plumbicon tube and Marconi Made the MkVII 4 tube colour camera.
It used the 101 cable with the slow thread brass connector.
There is an announcement in Practical Television June 1962, stating that the Marconi BD848 made it's first appearance at the National Association of Broadcasters Convention in Chicago.

I will be writing more about this camera and adding more pictures later.
