About this detail of the Tiger
On the Tiger's engine deck there were three hinged hooks for holding open the engine hatch and the 2 fan cover grilles.
One of these hooks is shown above. There was a welded latch for each hook, as indicated at the left of the photo.
The latch was undercut so that it would hold the hook solidly.
This undercut is not represented in the kit. You should add it yourself.
In the Tamiya Late kits, the rearmost latch is missing and you should build it.
