One of the nicest things about being interested in transport is it often takes us to those places conventional tourists miss. One of these places despite it's historical importance being where the Swiss Confederation of Cantons was signed is hardly known never mind visited by Brits. Also it is the name of a small canton too which is why this bus carries it as SZ. Once Leyland seemed to have it's own empire of nations and a few even found their way into of all places Switzerland and this Worldmaster, one of a pair looks a bit unworldly carrying the sort of very Swiss bodywork normally found on Saurer DUK's and a few FBW's too.
