Default Advance E2 Signal generator circuit

After watching a few vintage gear restoration videos I feel inspired to have a go at my Fathers old Advance E2. I have downloaded a couple of circuits but there seems to be quite a difference to the one I have. The valves are: V1 - EC52, V2 - 6J5, V3 - 6X5. Its a yellow case with serial number 1275.

I am awaiting the delivery of a set of replacement capacitors, however the values on the circuit diagram seem to differ with the ones fitted.

Is there another version of the circuit diagram available anywhere?

Thanks in anticipation

I had an E2, pics of which are below, along with the E2 manual, kindly supplied by forum member.

Like most E2s mine was rather scruffy externally, but pristine inside, rock steady, and the accuracy was spot on.. Such well designed robust generators - the only thing not in their favour is their size and weight. (I don't have it now - I gave it to a chum). I don't have the serial number but it was stated to be a 'Model 1' which implies that there were other E2 models.

Hope that might be of some use.

Curiously, every article I can find has photos of the octal based valve version but the circuit of the all glass valve version, usually with the ECC91 marked as ECC82. Neither of these are the one that is the subject of this thread!
