Great post Alan!
Thanks for going to the trouble to post the pics.
It's a good example of something being 'beyond economic repair' is sent to a service agent due to high labour costs and VAT, but within the scope of a skilled DIY repair. You did well to track down a new bearing and brushes, and as you say, you've got a serviceable 2kW grinder for a tenner, with a list price of close on £100, and with soft start too. (I've got a cheapo Clarke sawbench which doesn't have soft start, and the 'kick' is very disconcerting when switching it on. I don't know if there are any means by which one can add soft start externaly. It does have an NVR switch).
The grinder must have been subjected to a lot of punishment to get into that state - prolonged use under heavy load, beyond what could reasonably be expected of it. It's an angle grinder - not a petrol driven Stilh-saw. Even a 5" grinder with a stone cutting disc can be used to cut 2" concrete slabs, but you have to go steady with it as cutting puts a lot more load on it than does grindidng, which is the primary intended use.
As you say, it's still in production - about the cheapest you can buy one is £75.00:
