Murph,
I see that the original bronze plaque memorial was lost during the renovation of London Road station and was replaced by a new memorial now containing 87 names and which is located on platforms 10 & 11 at Piccadilly Station. It would seem, too, that the lost plaque also honoured some 580 men who had survived the conflict and had worked at the station. Apparently, a photograph of the names on the missing plaque had once been taken. Perhaps it would now be appropriate to contact the authorities at Piccadilly station and seek their help with your interesting query. PhilipG.
