Can't think of any.
Besides, Fernando di Leo has stated repeatedly, that the spaghetti western was (among other things) a reaction to the fact that the Americans had 'transported' the western genre to television. Those TV-series were very popular in Italy, so if the Italians had produced their own series, they would have been in competition with Rawhide, Bonanza etc. Not easy! Since less westerns were released theatrically (and those that were released, had become more and more psychological dramas instead of action movies) the Italians thought it would be a good idea to produce their own. The German-Yugoslavian Winnetou movies had shown that the genre was still popular among European moviegoers. Actually, the western was more popular in those days in Europe than in their natural habitat, the US.
