Flak is good, and new flak gun kits better.
Having built Dragon 2cm Flak 38 kit(s) (flakpanzers, flak track, flak guns), I'll bet this one will be a good addition to the shelf and collection. And I may eventually get one. (Though I firmly believe it will be really hard for Dragon to surpass the Tristar 38-late kit

)
But Dragon could, I think, get a LOT more sales of a 2cm gun kit were they to put out a "main stream" Flak 30 kit, with proper turn-table and gun-shields. Just saying. I know I would buy 2 or more of those!
Of course, Dragon having tooled the 3.7cm guns for its flak tracks, maybe they'll release a stand-alone of that gun!
