Found in Normandy, Manche, France, 14mm.
CHEMINS curving downwards / OUEST straight across centre / DE FER curving upwards // 3, five pointed star below, FASO?* DES BILLETS around
From the finder, "From a quick skip through the internet it would appear that it was issued by the Ouest, Chemin de Fer railway company and dates to around the late 19th century."
From Michel Royer, *"read 'FABON' for 'Fabrication des billets' (Manufacturing of tickets)." Not FASO?
