About this detail of the Tiger
In "mid" and "late" Tigers, the gun counterbalance was beside the commander, fixed in a sturdy boxlike structure (a trestle). Rye Field have provided Part U26 to represent this structure.
In order to match the curvature of the turret, this trestle was made with a parallelogram cross section, not a rectangle. Here is the base of the trestle, where it is bolted to the turret floor. You can see that the angles on the bottom plate are not right angles.
Unfortunately, Rye Field have designed their part with right angles at its front edge. Their back edge is necessarily slanted to fit the turret floor. Therefore the left side panel of Rye Field's part is thinner than it should be.
