Re: 232L bakelite telephone and No 26 Bellset
Those diodes would do fine. They're not essential, but a 'nice-to-have' and reflect the GPO's improvements to the circuit.
As for your 232, you don't need a bell capacitor, as the cap is in the master LJU (see attached diagram). If you get yourself a tatty old 700 series telephone cheap, you could gut it, apart from the bell-motor, gongs and terminal strip (or PCB), as the 7XX contemporary bellsets were, effectively, but with a plastic cover over them for wall-mounting.
