The largest run of subjects belongs to 1:35 tank tracks: workable sets for the M24 Chaffee, 3D-printed links for Tiger I, the T-34 in early and waffle patterns, the KV-2, the M18 Hellcat and SU-122 tank destroyers, all-steel HVSS Sherman links, the Comet, the BT-7 and snow tracks for the M26 Dragon Wagon. Each listing names the kit it fits.
At 1:35 the link pattern itself carries the character of the vehicle, so plain, waffle and extended types are all represented, down to the less common production variants. Workable runs settle onto the suspension by themselves, while glued links need shaping before the cement goes off. Find the subjects in 1:35 military vehicle kits and the full spread of sizes under model tank tracks. Dust and soil go into the links most easily with weathering pigments.
