Wirbewlind (ger. "Hurricane") was one of the best WWII AA vehicles. His 4x 20 mm guns were real deadly wind for enemy planes.
Here we have Tamiya model (1:35) in early spring camoflage. Front is unknown.
Please note special scope, which i have made myself. I cut hole in plastic, flat scope, cut off round glass and put it here. It looks nice... in my opinion, but later i have read, hat this guns hadn't optic sights
So in different photo you can see this sight without glass.
