Used this on my 1/35 Tamiya ausf A and they fit well. Requires 85 links per track which leaves you 10 track links left over to replace the ugly individual kit links that are hanging on the side of the tank hull. Don't know how authentic these tracks are to the ausf A but in my opinion they look great with a nice sag on top. Easy to assemble however you need to be careful when snapping together as the little pins can get sheared off. Since my I'm displaying a static model, I glued most of the track links together so not a problem for me.
