All the way from the Emil to the early versions of the Gustav, Bf-109 wheel hubs had support spokes in the hub. These are very deep and are very difficult to replicate in plastic form. Eduard has done a superb job of capturing this feature in their Brassin line.
Contained in a plastic blister pack are two main wheels of the proper size, 660 x 160, the tail wheel strut, and two spoke assemblies which are protected by foam backing. Also included in the kit are a set of masks to use on all the tires. The instructions are easy enough to use and show the proper orientation of the finished tire.
