Luftwaffe Fl number list for toolboxes and groundcrew Equipment

[BOBC]

Hi,
Luftwaffe Groundcrew toolboxes, the metal ones with carrying handles and also the wooden boxes with racks inside holding various tools, had Fl numbers on them.

I need to see a list and better still the box image and interior for all toolboxes.
some examples are Fl.68510 the classic metal one with looped handle, Fl.68530 metal 3 tier one,



I see a Flzg-Metaller Fl.68680 and wish to know what the interior looked like.


If stepladders and wheel chocks had Fl numbers as well as other ground equipment I wish to form a list of what existed and its appearance.



As an example I have identified (have photos of) so far 10 different toolboxes and 15 different stepladders and wish to see an official list to establish the full range, appearance and Fl numbers.


Any leads on where to find such Fl lists and images appreciated.


Also as mentioned Fl.68680


Cheers
