In Frances I've added the Rolls following previous class in site 40/50 h.p. 'Silver Ghost' http://www.imcdb.org/vehicles.php?make=Rolls-Royce&model=40/50+h.p.+'Silver+Ghost'&modelMatch=1&modelInclModel=on

Until here all is OK. But if you click only in these parts of the model name: 50; h.p.; Silver or Ghost you don't get any result and, on the contrary, a strange 40/50
