Who made these? Probably 60's stuff

[mr dann]

Am looking at perhaps seeing if I can get some replacement friction surfaces. If not, might have a go at getting them refaced and then nitriding them myself.

Both the flywheel and the backplate are aluminium and have the same wear surfaces as steel inserts. I'm not sure whether Leyland ST made these as I thought the surfaces were sintered. Any ideas would be helpful as I'm curious whether I can just go and get some surfaces off the shelf or whether I have to get my cash out.
