crosfield oscilloscope

[larya]

Greetings...
Recently a ham friend of mine gave me an old oscilloscope.. By the
looks of it, I estimate it to have been build during the 40's...
Grosfield made in England..type TA.. Does anyone know of this scope?..
I would like to get the schematic diagram...There are two tubes
missing.. They are located on the top and by the position of their
tube sockets are positioned over the CRT...

Could it have be a rebadged for export to Canada, something else eg anything

perhaps Cossor as partial anagram (maybe cossor was a pre-existing trade
name in Canada)

A list of the valves may be useful

I think - by the position of the (missing) valves it is most likely this one:-
