About this detail of the Tiger
The Tiger's HL210 engine was topped by three air filters seated in a large duct.
Rye Field have provided these items, with part H36 representing the duct.
But Rye Field's duct has vertical sides. The real duct had slanted sides, with a 30 degree slant on the narrow portion. You can sand down Rye Field's part to give it the correct shape. (Its mold seam needs sanding in any case.)
Another small improvement would be to drill out the open end of the duct, which should look like this.
