About this detail of the Tiger
There is a small problem on the rear hull wall.
The Feifel mounts on the top of the wall and the ones lower down are not aligned. These distances should be identical.
By comparing to this diagram of the true Tiger positions, we can guess what happened. Border's model has side walls that add to the overall width. If their designer forgot about the side wall, it would explain why all four of these mounting points have been pushed away from the side, especially the outermost one.
If you are building a Tiger without its Feifel filters, you could improve its look by repositioning the outermost mount at least, to make the set symmetric.
