As Mike has stated these hubs were made in France. The manufacturer was Ets Perrin ,based at Boen, in the St Etienne conglomeration. They were one of the many sub-contractors to the French cycle industry that were in that area, providing accessories to the cycle manufacturers such as Automoto, Mercier, Cizeron, Manufarnce etc etc., Other compamies were Vitus, Lyotard, Stronglight, Super Champion, Perache,Rousson et Chamoux(Maxicar), Peyrard (Nervar), CLB,, Ets Haubtmann (Solida), Belleri,. Many others such as Mafac, Simplex, Mavic were based not far away at Clermont Ferrand, Dijon end just north of Lyon.
in the 40/50s and into the 60s I recall the name Excelto being used extensively, but then this was dropped in favour of "Pelissier", a brand that continued into the late 80s, until it couldn't compete with components from Japan and Taiwan. The company made all sorts of hubs, having a complete range including hub-brakes, as well as hubs for invalid cars, sulkies, wheel chairs etc. In the late 70s the company introduced its 2000 (I think it was 2000, maybe 2001 range) of top-end large and small flange racing hubs. They ran on rectified sealed-bearings and were considered to be some of the finest hubs available from any manufacturer.
