Yes, wrong way round. With Stephensons Gear (Williams Gear, actually, stolen by *Robert* Stephenson), the longer the cutoff, the less the Lead. Quite frequently, in Full Gear, Stevo has *negative* Lead; that is to say at Dead Centre, the valve has (not quite) yet opened the inlet port. This is a VERY favourable circumstance to induce as smooth a torque throught the crank circle as a steamer can achieve. Once speed/notching up occurs, Lead is restored to positive values: - best of both worlds
Very nice footplate footage! I do like George Stephenson. Unique with the different valve gear
