Murphy did likewise.
Same sets but with variations depending on where they were made, and for which market. The service sheets often refer to the Irish variations.
It all helps to make life more interesting - things rarely go smoothly, but therein lies the challenge!
As a favour to a nephew, I'mm presently restoring a Ferranti 045, and was pleased to note the seven-page maker's service data, until I noticed that there's no under-chassis view to identify the 36 resistors, 54 capacitors and 20 coils, (and that doesn't include the FM tuner unit!)
Most components are on two long tagboards back to back, with some components sandwiched between them. It's possible of course to work out which is which from its value, and by tracing the wiring, but a diagram would have made life much easier. Having replaced several caps and a few resistors, and fixing a couple of loose wires, it is now working on all AM bands and on FM, but I'm awaiting a NOS Russian made EM80 magic eye from Siberia of all places, (a pack of four actually), and a UK sourced ECC85 for the FM tuner unit as the existing one is on its last knockings. Ah, the wonders of E-bay!
I was given a Pye Fenman1 and a bag of 25 boxed NOS valves for my efforts, so one good turn deserves another, and really, I got the best end of the deal
