The Tiger's sprocket wheel was altered a few times in its early months. The cover of the central hub, in particular, was changed a lot.
In April 1943 they settled on this design. The hub is flat, and has a protruding central disc, also flat. This kind of sprocket was used on all "Mid" and "Late" Tigers.
But this kit provides only one kind of sprocket, a type used early in 1943. This is the kit's part. The hub is a rounded dome. This type was used on the famous "Tiger 131" but not on any Late Tiger.
