My experience is limited to a few later cwps but the original Austin seem quality products, with fatigue pits developing before serious wear. I have only seen very distinct wearing in with a couple of Regent cws which seem not to be hard. Ran OK nonetheless. Were smoothed with emery paper and reused.
If there is significant wear setting up can be a ritual and really little option but to set as was. Can be very time consuming and care necessary not to overtighten a.c races. Wear steps on pinion particualrly should be ground off with a slipstone or Dremell, otherwise an adjusted gear may ride entirely on these.
On the old chestnut of diff oils and effect on bronze, I recently stumbled upon Youtube GL4 and GL5 Transmission Lubricating Oils Explained ,which dwelt primarily upon a wrecked US gearbox. There are comments about corrosion. (Oddly the expert ommitted that GL5 avoided in gearboxes because it polishes synchro)
