hmmm.. on my champion hoffritz the tang stamp on the front is Hoffritz an the back is switzerland, stainless rostfrei. on the one on eBay you can see the "vic" on the front scale, end officer suisse crossbow on the back. what does that mean? 
It means that your Hoffritz Champion was made before this one was. Victorinox stopped stamping the main blade with "Hoffritz" in the early to mid 1980s. They also used to inlay the word "Hoffritz" in the front scales, and around the same time they started hot stamping it instead of using the inlay.
The seller didn't change scales or anything - this is just a standard Champion made for Hoffritz
after they stopped stamping the main blade.
