Info for the Cossor 172K was obtained from Radio Valve Data, Eighth Ed. in section Television Cathode Ray Tubes page 57. Base diagram number is B12A number 10.
In the meantime I have been turning the place upside down to find the original Cossor Valves and Tubes book c.1956. Success! So far it confirms data in the ILIFFE publication and has a bit more info! Will try to scan later.
Also discovered another Cossor short form data book published in 1959 by which time 172K was obsolete. However information on receivers that used this CRT including 171K, advises it can be replaced with MW43-69 in the following models, 930, 933, 934, 935, 937, 939, 942, and 946.
