Matrixone, as promised, here are my photos!
There are pics of most of my German AA Artillery in 1/72 scale. Each of these kits was put out by Esci/Ertl, and most, if not all are still being released by Italeri I believe. All these models you see here are more that 20 years old so they may not appear as quality builds.
I'll start with my Quad Flak 38 which was part of Esci's 1/72 scale German Artillery set:
Here are two pics of my German Sdkfz 7/2 sporting the Quad 38 in the first pic, then the single Flak 38 in the second pic:
Last of all is my German Wirblewind:
I haven't started my Ostwind yet, but when I do, it will be able to be seen in one of my 'Factory' Threads!
And for you wrbridge, here is a pic of one of my Opel Blitz trucks. It hasn't been detailed with a wash and dry-brush yet, but you can see how it builds into a nice little kit:
If I can find anymore models to shoot for you, I'll post them here so you can see them. Still, with my post and t3488's post, you have a pretty good cross-section of German WWII Anti Aircraft Artillery!
