Dora-13 I know we're supposed to repeat the inscriptions just like they appear on the box. So this is a technical note to the manufacturer (And for anybody who cares to know): The proper designation of this gun should be 88mm L/74 Flak 41 instead of "L/71". The PaK 43 / KwK 43 had a 71 caliber barrel length. The Flak 41 however was an entirely different design, and had an even longer barrel. It also used different ammunition than both the Flak 18/36/37 and the PaK/KwK 43 families.
Bronco does include a sprue with a handful of cartridges, which is nice. However, these were designed for their PaK 43 kit, and are not appropriate for this gun.
