Hand-held anemometer with four hollow hemispherical cups fixed to rotating cross arms that are mouted on a flat, paddle-shaped wooden base. The original timer is missing and has been replaced by an egg timer consisting of a metal disc with a single hand fixed to the centre of the disc and numbers engraved around its circumference from '10' to '60'. The timer is attached to the base with wire. A note accompnaies the anemometer.
