A knife made by Girl Scouts that Snip Boys?
It might be 'Graef & Schmidt', who (according to Levine's Guide to Knives) were a German/American agency for Henckles from the 1880s to the 1940s, and also made knives in the 1940s-1950s. G S can also stand for Guss Stahl (cast steel, though that probably doesn't fit here).It does not match any of the half-dozen names on my list of official Swiss Army knife makers.Regardless, a very nice find!
