Product Description
A Great Western Railway 1947 pattern block indicator, these fine instrument were introduced in 1947 as a replacement from the standard double line "Spagnoletti" blocks which had given reliable service for over 70 years. These instruments are very pleasing aesthetically pleasing and ergonmic to use, as an ex signalman myself there were a delight to use and easy to see from either end of the lever frame. This example has been examined in our workshops , cleaned and all coils tested and proved working. The case work is in first class condition and all moving parts operate smoothly.
