GWR Signal Box, Tyers 16 position Mahogany Cased Train Describer ivorine plated Chester No 3. An identical example with the exception of the signalbox number, is on page 181 of LNWR Signalling by Richard D. Foster. A quite magnificent and substantial item. The front, top segmented dial is populated with the following:- Holyhead Passenger Train; Mold Passenger Train; G.W. Passenger Train; L.N.W. Light Engine; G.W. Light Engine; L.N.W. Goods; G.W. Goods; L.N.W. Empty Coaches; G.W. Empty Coaches; Through Coal Yard; Signal In Error. Beneath this top dial is an ivorine plate Down Fast Line. The bottom dial is annotated in the same manner. The pull-out clockwork mechanism appears to function correctly and the condition is wonderful.
