A late 1950 G.W.R. pattern lamp in/out repeater which was possible manufactured by the railway at their Reading Signal Works, reason I say this is because there has never been the usual R.E.Thompson & Co brass makers label. I've never come across this before and could be one made prior to letting Thompsons manufacture them. This instrument is in excellent ex box tested condition and has a number 50 Traffolite label. The "white" powder is Brasso !
