There are 50 of them many not seen before.
I am still looking for information on the smaller of the two colour cameras in the colour studio pictures. It is one I have not seen before, circa early 1960s. The larger of the two cameras is a Marconi three-tube 3" IO RGB camera the BD848.
Two pics of the unidentified camera attached.
