England were still using and making Iconoscope and Orthicon type tubes right into the late 1950s, PYE kept on improving the Iconoscope tube making the Photicon in the late 40s and Pesticon in the early 50s, EMI improved on the Orthicon design renaming it the CPS Emitron and made CPS emitrons well into the late 50s and produced the Type 10678 camera in 1956. From what I can see, during the earlier to mid part of the 50s EMI and PYE (with the exception of the MK3) pressed on with those older tube types whereas Marconi was the main British brand to adopt the Image Orthicon when they started producing cameras in 1948.
