Well, here's the result of my attempt to replicate it:
PSC gives you empty shell casings in the set, which really helps with the atmosphere.
And here's the view of the whole destroyed gun.
The availability of cheap plastic kits aimed mainly at wargamers makes creating wrecked vehicles and guns as terrain pieces affordable. PSC is planning to release German trucks, so I hope to do the same thing with one. Problem is, you actually need a detailed kit if you want to reproduce a wrecked truck, because it's when a truck is blown up that you can really see the innards and axles and all the other bits which you hate having to glue together for your wargaming pieces. Take a look at this:
See what I mean? Now you know why they made the tyres separate from the wheels in Tamiya kits!
Anyway, if you do come across a photo of a destroyed Opel Blitz or similar which looks like it can be reproduced in 20mm, please send it my way. Thanks.
