Devil´s advocate eh!, no problemo.
I don´t think I was clear enough in my last post; the bracket type 1 (see earlier post) you also find on left side, they look exactly the same both of them - a small U bent strip on supports where the slit is only 6-7 mm wide and you put something into it from above. The only thing, in my mind, that fits the bill is that saw and it would look like this;
The saw looks like this at the end;
This means you have to have the ends outside of the bracket type 1.
As for the saw being there in the first place, perhaps it´s for cutting down small trees used for camo when in hiding or larger trees for making/supporting roads in the terrain where Jagdtiger´s weight was problem.
Still not convinced or?
