Its a Wenger Metal 50/Stainless Traveler for the 700th anniversary of Switzerland.
Your's appears to be missing most of the logo on the handles, either worn off or polished off. Still a good user, though more than a bit heavy. I normally carry a Traveler. Carried one of these for a few hours and swapped back to the original. Definately a load.
There are a number of other 'coffin' Stainless Travelers, some commemoratives, others commercial.
