Victorinox produced model no. 203 between around 1940 and 1970. In principle, it was the basic model no. 200, except that a narrow screwdriver was fitted instead of the can opener. Victorinox manufactured the No.203 model using carbon steel or stainless steel tooling.
The difference between the Model No. 203 and the Model No. 202 ½ was the screwdriver, which on the Model No. 203 had a notch for stripping wires. It appears to have sold significantly more than the No.202 ½ model.
SBB, the Swiss Federal Railways, was a major buyer of model no. 203 pocket knives.
Pocket knife No.203 had a large cutting blade, a screwdriver, a narrow screwdriver, and an awl.
Large cutting blade: 3.4 - 3.7 mm; Awl: 2.1 mm; narrow screwdriver: 3.0 mm; Screwdriver: 3.0mm
Pocket knife No.203 was a 2-layer model. The upper layer consisted of a screwdriver and a small screwdriver, the lower layer of a large cutting blade and an awl. The screwdriver and the large cutting blade turned around the head rivets, the other 2 tools around the foot rivets.
Victorinox used red fiber as the scale material for this model.
