Product Description
This Great Western Railway double line block indicator dates from 1900 to 1920 and has the classic ogee profile making this very handsome and well made. This example has escaped being rebuilt and modified at the G.W.R.s signal works at Reading with extra contacts on the rear. These contacts were added to enable all the extra changes in signalling safety. This instrument has been inspected and all coils tested on an Ohms meter.
