Face diameter 155mm
Length without base 415mm (increase with base 5mm)
Maximum viewable picture with a 4:3 aspect ratio 120mm diagonal. Actually a 5inch picture although if the picture size is increased so as to wrap around the curved front of the tube somewhat there is enough phosphor to display a picture of 6inch diagonal as specified for the televisor.
Note that the aspect ratio was 5:4 in 1948 and was changed to 4:3 in 1950.
Note also that a mu-metal shield is required for this picture tube.
