Little Help?: Alvia/Express Werke Bicycle

Mauricio, whose Huffy Sportsman project was recently featured, has also picked up this very unusual three-speed bicycle of unknown vintage. It's sitting in my garage while I do some research on it, and try to determine what it needs for a restoration. Here are some pics and brand names we've found on the bike:

Head badge: Alvia

Seat tube: Express Werke

Shifter/Hub: Tornado (or Tornedo?) Edit: that's a Fichtel & Sachs "Torpedo"

Dynamo and Lights: Schmitt's

It looks to have been set up as a higher-end commuter for its day (whenever that was). The rims are aluminum, as are the fenders, and the bars look like the little riser bars you see today on fixed gears. I'll throw it open to the group. Any thoughts on age? The shifter and hub indicate "Mod. 55" but that doesn't seem to be the year. Edit: the F&S Torpedo Model 55 was used between 1955-1962. There's also a peeling decal on the front fender that appears to be an American Indian. Little help? Anybody?
