Big fan of the Red Gambit Alternate WW2 series
http://www.redgambitseries.com/ where the Russians invade further into Germany in July 1945. One of the nicest concepts is the whiffieness of it all. I have done other models based on this inspiration and here is another one.

During the desperate times holding the line after the treacherous Soviet attack, the New German Federation and their "SS colleagues" now in the French Foreign Legion worked hard to get vehicles up and running. Any vehicles. Often this involved lots of modifications to match together, often mismatched components.
One of these was the Aardvark, which comprised using tried and true Panzer IV hull with the Achilles Tank destroyer turret with its formidable and still effective 17 Pounder weapon. Of course not a perfect union, but, it did enable quite a number of similar vehicles to outfit the Cameroon Brigade of the Legion with a Tank Destroyer battalion.
