This just about creeps in to the Sporting theme I think. No connection I'm aware of with the model name but this is not a domestic machine being designed for fine turf. The engine drives the cutting cylinder only. I've been looking for some time for a suitable piece of leather to renew the drive coupling. The wooden T handle is original as far as I am aware, in spite of the Pennsylvania marking.
