This is a Victorinox Tourist, which is basically a smaller (84mm) version of the Spartan, in this case without key ring. It has horn scales and the tweezers have an aluminium handle but I think that’s not the original one since this knife is newer.
I bought this knife hoping it was 91mm, but since it is not (and in rather poor condition as well) I may put it up for sale/trade later.
Two nice vintage items. Both with horn scales and in 84mm.
The older one (stamped Inoxyd/Armée Suisse) has the pre-1940s opener layer, the old style reamer and brass liners. It has a taper towards the end, with the blade layer being quite a bit thicker near the small clip point blade pivot. This is a beautiful vintage knife in great condition. The only flaw is the missing tips on both blades.
The other one is marked Victoria and is probably from the late 1960s or early 1970s. It has a +PAT opener and small clip point blade. The liners appear to be alox.
