Equipment model; Buoy model

Scale: Unknown. Working model of a bell buoy, made to show how tidal action operates the bell mechanism. When the buoy is moved side to side a ball bearing in a box attached to the top of the buoy moves from side to side striking two hammers which alternately strike the bell mounted above the box. The buoy has been painted showing the waterline as a white line around the buoy. It has been painted ochre below the waterline and red above it. The bell mechanism is made of brass while the box containing the steel ball bearing is made from wood with a glass panel. The buoy has a securing ring on its cone. The base has a pair of cradles which allow for the rocking motion of the buoy. These are mounted on a regular trapezium shaped baseboard with narrow end mounting the nose cone of the buoy. Behind the rear most cradle mounted on the baseboard, a medal in a wooden frame is inscribed "Prize medal awarded to Mr W.H. Whettern". The baseboard stands on four turned button feet. The metal work of the model is tarnished, while the paint work has cracked.
