Modelcollect offers 10 models where it uses Flak 40, the models are 1:72 scale, I recently released photo-etched sheets for these models.

PE Parts - flak 40 1:72
Modelcollect 10 in 1

Cool, those parts will help grade the models! Where can i get the PE and how much is it selling for?

This would have been really useful a year ago. Unfortunately, Modelcollect has taken the FlaK 40 (both twin and single) off their catalogue which seems to indicate it is out of production, although some may still be available from some vendors. Modelcollect still list a single FlaK 40 on a what-if E-75 chassis. They keep advertising models that never materialize, and deleting really useful models, and concentrating on "what-if's", and "never-were's". What are they thinking??
