All I can tell you is they appear to be built on the 0.68xx frame, which was common in an earlier time for ladies and gentleman's knives. That's a very nice find as those knives are very pocket friendly. It appears the knives were made with many different scales, but often from natural materials rather than aluminum. I hope you find out more information, but I have a feeling there may not be any official name for that. You could ask Victorinox if they know of any name being associated with it (or at least get the correct AN), but they don't seem to have paid much attention to the earlier names that were assigned by the importers. The proper AN though may help you find a name if one exists.
