Well, progress I guess.
The bearings were shifted by getting a scrap later type diff case and gluing into the bearing with Loctite. Then (24 hrs later) I could utilize a pair of tyre levers to force the bearing out by levering on the diff case.
Then, I took Ruairidh's suggestion and heated up the side cases with a blowlamp to get the wretched grease and oil mix out. It's horrible, horrible stuff, won't flow unless it's hot. The fumes were....interesting.
That left the diff and half shafts assembly to degrease. I used a hot air gun to heat it up to get the mixture to flow and drip into a tin (where it solidified again). Then washed the whole thing in diesel, several times, keeping it hot. The fumes were......even more interesting.
All now looking a lot cleaner but it has revealed that a bodger has been at work inside the axle.

Sorry about the fuzzy photo's, the light is bad in that end of the garage.
I knew that the car had come off the road in 1931 due to some back axle malady; I had somehow assumed it was a broken axle key but it looks like someone has had the diff case apart, probably to change a halfshaft. Two or three of the lock tabs are broken and a nut is on back to front.
Fortunately, the tab washers are available so all is not lost.
The bearings are all in good order but the crownwheel is quite badly bitten into, lubrication failure? The car had done very few miles when it was laid up but I'm expecting some axle noise when it's finished.
