Looked at the auction pictures. Definitely a Picnicker. It's probably from around 1972 - I don't see a "+PAT" on the can opener. This model was made into the mid 1980s, but by then it was in the regular Officier Suisse line. Since this is still stamped "Elinox", has a 5 turn corkscrew and a cap lifter with wire scraper, its probably a c. 1972 model. If there IS a +PAT on the can opener, then we need to look at the other tools to try and narrow down a date range. Specifically, are the can opener and cap lifter machined or polished. This knife was made right around the time they started polishing all tools on all knives, including Elinox.
