That's weird. My 1942 model (which isn't a "P" or Privat model) is marked "ELSENER SCHWYZ over SWISS MADE" and then "SWISS MADE" on the screwdriver, and has carbon steel blades and steel pins/liners. At that time, Victorinox wasn't really the company name, just a mark they used on the stainless knives.
According to the 1942 catalog, there was a stainless version of the Model 200, the "200 inox" that was stainless instead of carbon steel. While the Model 200 was pretty much the civilian version of the M1908, I'm sure both the carbon and stainless versions were purchased as replacements for lost or broken M1908s.
Here's a page from the 1942 Elsener catalog I found at the SAK Wiki, that shows what I think is your knife.
