Re: Baird Garrick
The CRT is the Mazda CRM121 or CinTel 12MW3A.
The HT rectifier Mazda UU8. RF pentodes Mazda 6F12 = EF91/6AM6.
It's possible the timebase circuits are similar to the pre-war Baird TVs, those pole piece extensions about the neck of the CRT will confirm if that is so.
The timebase valves are likely to be the Mazda 6P28 although it's worth noting that Ambassador employed a similar circuit in the TV2 and the valves employed in that set were two 20P1s.
The revised attachment shows the frame transformer pole pieces.
