The Victorinox Champion (type a) was a flagman of all 91-mm models before SwissChamp was released in the middle of 1980xx.
As SAKWiki mentioned, it was a very strange practice when the same name Champion was used for the different models – with corkscrew (Champion a) and Phillips screwdriver (Champion b) on the backside. Usually models with such tool’s replacement got a different name (like Spartan / Tinker).
