The Peruvians were early adopters of Mausers, by way of Argentina and their pattern 1891 (a derivative of the Ottoman 1890, which itself is a Belgian 1889 but without the barrel jacket). These early Mausers used a slightly different style of stripper clip than the regular pattern (introduced with the Spanish 1893), which is held in place by ejector/bolt stop. The 1893 pattern is instead held in by just dropping into the stripper clip guide (no spring tension), and has little nubs on the side to act as over-travel stops. When Peru (and a couple others) moved on to later Mauser designs, they wanted to continue using the old style stripper clips, so they had their guns made with different clip guides, some continued using the split system with the ejector forming half of the clip guide, and others (such as your Peruvian carbine) just having an extra tall clip guide.
As for where to find the clips you are looking for, that I do not know. However, you can either find original Peruvian, Bolivian, or Ottoman old-style clips, or you should be able to modify later pattern clips by simply grinding off the over-travel nubs on the side.
