History and Performance
The Encyclopedia of German Tanks of World War Two, by Chamberlain, Doyle and Jentz, show that 319 Sd. Kfz. 7/1 fitted with quad 2 cm FV38 were produced until October 1944, and 123 Sd. Kfz. 7/2 fitted with 3.7 cm FlaK 36 were produced until February 1945. This review addresses the latter vehicle. These vehicles were issued to FlaK units of the Luftwaffe.
I scoured many of the personal library references and found very few images of these vehicles. Nonetheless, this looks like a very interesting build.
