Cossor did not supply circuit information for all their models.
From 1939 onward Cossor often just adapted existing models, some models have several distinct variants with the same model number.
The model 74 has at least 3 variants that I know of.
Cossor didn't see the need to issue service information for these variants as the competent serviceman would just work with what he had finding the nearest circuit if needed.
Replacing a 4XP with a 2XP or even a 2P was common especially in 40/41 before they discontinued production completely.
So even if you do get a circuit diagram there will be no guarantee a 4XP will be fitted.

It's rare and desirable
