Period Swiss ski tip emergency repair part. The basic idea is that if you break the tip off your ski, which was relatively common with early skis, you could use this to replace the missing tip and get yourself back on the move quickly. This is made slightly different from the WWII German one in that it clamps the ski from either side rather than screwing down from the top. Made from aluminum in good condition.
Price is for ONE tip (they are not sets).
