The diaphragm rubbers were deffo shrunk, but otherwise in fair shape.
Revitalised them with Autoglym Vinyl and rubber cleaner - really made them supple and they're not all that fragile as some lead us to believe.
Once lubed with Autoglym I stretched each rubber onto the opening of a tin for our tea bags for about 20 min's, gently teasing it further and further around the opening of the Williams specialist tea tin.
You can see in pic 3 how the rubber is too small, but pic 4 is about 20 min's later.
Gotta sell this one to Guy Martin

Get yourself one and enjoy a cuppa at the same time, it worked for me!
