Hi apollo111
Thanks a lot for posting the image of the 3.7cm Flak gun of 22 Dec 2020...

I think it is a very rare and interesting image.
Is this gun of Greece Army ?

All images of these guns in service with Greece Army that I have seen have different wheels with solid pnematic tyres...
I have seen this gun model in service with Greece, Romania and Italy but I think this gun have some differences with those guns of these countries.
In fact, I have never seen this type of wheels on this gun
Nor had he ever seen an associated limber for towing the weapon. It seems that the limber was designed for horse drawn but instead the wheels, with rubber tires, suggest motorized towing....
