Yup, those be the locking pins, donno who made the tracks unless you are willing to post or email a photo. Stock KT tracks last worlds longer with reversing the pins, but metal and locking pins, you should be OK. Just keep an eye on them, as with the real tanks. After every run, check the tracks and pound in any track pins that have walked a little.
What? No groveling before the Goddess of Massandra?? You don't understand. There's wine, and then there is Massandra. As good or better than any Mosel you will ever find, and before I came here, Mosel was the bench mark. Massandra is actually an old Czarist pallace on the south coast, now a museum. The oriiginal Yalta meetings between Stalin and Churchill et al were held there, but then moved to Yalta "for convenience". The valley east of my city has been growing wine for 2500 years or so, and it be pretty good. So, I guess even though you state it is not necessary, I feel the need to do penance for my mistake, and will grovel before the Goddess. The grapes for Massandra come from said valley, as do Inkerman grapes. Inkerman wine is good. Massandra..nectar of the Gods. Both are owned by the Church, by the way.

On the Tiger 1 tracks, the stockers are pretty strong in their own right, more so than the KT tracks. They have just about full closed loop pin retainers. You don't need to reverse them, except for the convenience of the ease of seeing who is working out. Again, the stated advice of checking the pins after each run, and if it's a long run, sometimes during the run, should keep you in good shape. I personallly switched to metal on my Tiger 1's some years ago, like in '03 or so, for the mass, the added weight. However, I have one that is doing yeoman's service with the original tracks for the local children, and try as they might, they can not break a track...yet. They do, however, have a finite life, and eventually will be worn out and need replacing. The tracks, not the children, that is.
