Photos of WWII German Flak Guns?

[Mako]

I'm thinking these might just be the ticket for a German airbase.

Want to run some strafing missions against them, with Allied aircraft, so would like to know what the following look like, if anyone has any photos to share of the following:

20mm AA Gun

20mm Quad AA Gun

37mm AA Gun

Also, and chance the sand-bagged mortar position is large enough to hold these guns inside?

Do the guns come with crews, or do you need to purchase them separately?

Quad 20mm (GRA2) defending my HQ and the sandbagged mortar position (GRX23), complete with mortar, hiding behind a hill!  As you can see I've positioned the two sandbagged items with a gap for my mortar crew to peer through, by varying the positions you could easily hold any of the three guns.

You might also want to look at the Sand Bagged Street Barricade (2) (GRX22) seen here protecting my Command Post

those are really useful photos (especially when clicked upon)

Thanks for sharing those pics.

Looks like those will work.

Would still like to see what the 37mm AA cannon looks like, if anyone has a photo of it.
