This Bakelite Lamp repeater was produced for the GWR by R.E.Thompson, these instruments were made from Bakelite during the WW 2 due to a shortage of hardwoords. After the war there went back to wood as it became available and probably due to the large ammount of work hours to produce in Bakelite. This lamp repeater was used to indicate to the signalman that the oil lamp was burnig at the respective signal. These are fairly scarce and especially in this condition which is excellent. The instrument has been cleaned and inspected and coils tested on an ohms meter.
