Technical help from Rudge experts...

Sam E Radial is on hand to answer those nagging technical questions like "What is this fork mounted item on a 1931 250cc?".

When RW introduced their 250cc radial in 1931, ignition was provided by a Miller coil using a points assembly mounted in the timing cover. The ignition was turned on and off using a Miller switch mounted in the rear of the headlight. To provide an indication to the rider that the ignition was 'ON', a small 'tell tale' was added to the top of the forks. This 'tell tale', made of brass, contained a small 6V cycle bulb bridged by a resistor and illuminated a small red lens when the ignition was on. The light remained illuminated at all times (it was not extinguished on charging). The resistor was needed in case the bulb failed as the tell tale was wired into the ignition coil circuit. Now there's a thing!
