Model built in late 1950's by my uncle from scratch. Built of red cedar bread and butter. All fittings hand made. Originally radio controlled with a valve transmitter and reed receiver, see pictures, which I still have. I believe the radio only ever worked once as tuning the reeds was almost impossible, even for friendly friends at RAE Boscombe Down. Model was exhibited at the 6th International Boat Show, when the model stand was sponsored by Model Maker. Was awarded second prize and a pennant, see photo. The boat was given to me as a 21st birthday present, and a few years ago, I installed modern RC, and the model is now regularly seen at Chichester Canal Basin where it runs at scale speed, i.e. quite slowly.
