Product Description
A very early pattern double Spagnoletti block instrument , originally the Great Western Railway employed single deck Spagnoletti blocks for each line which the Signal department decided to combine iton one new type instrument. This was the result, a handsome instrument retaining its original brass fittings and unmodified contact box on the back. These early type are quite difficult to find these days and this example is a beauty! This instrument is in working order and both flags swing freely, the case has a very pleasing patina.
