Steve I see in O&M that there were 143 3H's under contract C7162. These look to be exactly the same as the 3SW but with a 3H engine (Triumph forks etc fitted) Same batch of frame numbers. I guess they ran out of 3SW engines and used up some pre war 3H engines. Then they used up some 5S engines. Ron

Hi Ron, yes it could be one of those 143 and assembled at Warwick it's frame number could have been TL 30812 which would fit into that batch.
