As the war progressed German ground forces paid a heavy price to Allied aircraft due to Germany losing air superiority. German forces and industry sort answers to the problem with the German Tractor with Fla-MG151/20 Drillingslafette Auf Sd.Anh.Ost being what I class as an add hoc solution. By placing a drilling anti-aircraft gun on a trailer;  in this case the concrete wheeled unit which I believe only served on the Eastern Front provided a mobile air defence platform. This would then be towed by any suitable vehicle but in this case we have a tractor doing the grunt work. The tractor would be sourced from anywhere including civilian use.

The moulding quality of the offering is excellent in all regards with the only concern being the finesse of some moulding both as regards removal and  adding to the model. Otherwise have fun with this build as you cannot get it wrong due to it being an ad hoc solution to a problem created in the field.
