GWR MESSINGGEHÄUSE THOMPSON TRACK CIRCUIT INDICATOR
GWR BRASS-CASED THOMPSON TRACK CIRCUIT INDICATOR A nice, typical Thompson large, brass-cased track circuit repeater, mounted on a cast brass backing plate. These were often fitted with angle brackets at the bottom for mounting on a block shelf, but others, like this one, were designed to be screwed to the back of their corresponding block instrument. I've always thought these repeaters are really handsome instruments...... Pivots and bearings are fine, banner swings freely and the coils perform correctly at around 3-volts.
