Interesting. Checking service manuals the Brimar 8D3 appeared in the first post war KB television receivers from 1947, the CV40. HMV did not employ the Z77 until the release of the 1805 in 1949 as did GEC.
Vidor used the EF42 in 1947 but most large manufacturers went straight to the EF91 from the EF50 in 1949. We will never know! Regards, John.
