Thanks for the explanation Lucien, that sounds about right as most of the motors with a similar construction that I've stripped to clean have often been smaller than the one fitted into the Ampro which may explain why I haven't seen these small trenches between contacts. There are a few suppliers of either just the tungsten contacts themselves or the full rivet that can replace what is currently fitted. I'm sure the tungsten discs can be brazed to what is already there without much trouble and I could keep some spares for the future should I encounter the same problem. I bet reconditioning options haven't been around for a number of years as there can't be many motors plodding on with these types of governors fitted.

I could take some photos of the governor for you, I think the closest match may be from the Ampro Stylist which I believe had two sets for silent and sound, it's possible that they could be identical to the ones fitted to this model, just doubled up.
