Thanks for the welcome, Paul.

Here's a picture of the inside for those who are interested. You can see a pair of contacts at the "4 o'clock" position:

I talked to WF Electrical today. Martin Lunel are based in France but aren't owned by Legrand. This exact socket is still in production, but is horrendously expensive. The rubber plugs alone are £39 + VAT! Consequently I think I'll have to find another solution. I'm now considering fitting the machine with brand new Legrand Hypra metal sockets instead. These sockets are cheaper than the Martin Lunel plugs(!) if I go for the regular range, or a bit more if I go for the "Prisinta" switched range. Probably I will go for the regular range.

By the way, I need some 30 A "Slydlok" fuse carriers for the same machine. Anyone know where to buy them?

Best wishes,

Chris
