A Hercules sleeve seizing problem caused by very slightly out of round sleeves was solved by Clayton engineers. I don`t know what we are talking about here; a thou? a tength of a thou? ; but that suggeste the sleeves were made at Clayton. Anybody know more about that?

The only pistons I saw machined down there in A shop were the Napier Deltic Diesel locomotive/marine engine pistons, they had a copper crown. CNC turned as two details all fit up together final turned as an assembly and the crown details machined on a double head (Duplex) milling machine.
That was in the early 60's, they went I think to Newton le Willows for assembly into the engine although Wiki says they were assembled at Dick Kerrs in Preston. Maybe so?.
