Bsa mercury mk2

[junglie]

Morning all. Quick question for the experts. Apon stripping and cleaning the mercury (low power issues) I noticed the piston head on was a plastic/nylon head with a leather buffer. New one I ordered is a alloy head with a plastic/nylon buffer. Is this just how they are made now? Or did I order wrong set? Thanks all. Kind regards Lee.

the nylon ones swelled through incorrect lubrication so were discontinued, i used the right size tap washer as buffer as the buffer washers break up with age too.

Thanks handy to know.
