Aveling and Porter GND Governors

[8_10 Brass Cleaner]

Mark,

The Aveling GND tractors were designed to have the old fashioned type 'swinging bollock' governors, I think from memory the valve fits horizontally into the cylinder just above the flywheels side trunk guide.

The adaptor father had, is to fit a Pickering. It had the ports you'd expect under a vertical Pickering, but then a pipe within a pipe and a flange that bolts onto the cylinder. Quite how the two pipes were sealed in the cylinder remains a mystery to be, butthen I havn't seen inside the cylinder.
