RA 7802D O P C PUBLICATION "SOUTHERN SIGNALS" BY G. PRYER

This O P C publication is another fine treatise on railway signalling, this one Southern Signals was written by the late George Pryer and is the best publication out of the Southern Railways signalling and all the pre-grouping companies they absorbed in the 1923 grouping. This book is in very good condition with a little fading of the dust cover.
