A new Big 7
#6
The patent plate is screwed on - looks original to me. 

   

The core of the engine has not been touched before, all the tab washers are properly turned over, not hammered. Nuts and bolt heads are untouched by spanners, quite remarkable.

The clutch driven plate is very heavily oiled up, gearbox front oil seal needs looking at I think, would explain the juddering. The box was overfull.....

There is no oil seal at the rear of the engine - just a large thrower. I guess, if the crankcase is pressurising (someone had stuffed a piece of the lounge curtains (1953 style) up the vent pipe), this would also push oil into the clutch area....
