In regards of colour cameras, during the 50s in USA the RCA TK-40 and TK-41s were THE colour cameras of the 50s and 60s and even 70s because they produced bloody good pictures
!!! The other competitor of cameras during the 50s as one of you's said is the General Electric PE-15A
which obviously is based off the TK-40/41 design. Also in the early 50s CBS had their own colour cameras for their colour wheel system and they also have converted some B&W IO cameras to colour using a colour wheel in front of the camera IO tube. In UK when BBC was experimenting with colour in the 50s they Marconi made colour cameras which were also based off the TK-41 design.
As for B&W cameras, well quite a lot of brands: Marconi, RCA, Dage, Dumont, PYE, EMI and many more, check Chuck's camera brands page

I too wish I owned a TK-41 camera myself, would be bloody awsome especially if it were working as it would be so interesting to get first hand experience of what living colour was like in the 50s. If Chuck gets a few of TK-41s going and is willing to sell any and I happen to get rich I will buy one of his working 41s and get it shipped to Australia and use it wherever I go shooting anything in living colour 50s style
! Though I'd need an OB van as well.
What would be real cool is when Chuck one day gets his TK-40/41s going is have them featured on the news or doco which they can compare the picture of a TK-40/41 to a picture of a modern CCD studio camera which the host/news man would say "this is how living colour looked back in 1954" while being shot on a TK-40/41. Don't know how Chuck's going with his restoration on his TK-40 lately but hopefully he'll get it working sometime soon. I'm real stoked he's got 3 of his old TK-30 cameras from 1947 up and working
