Thanks for the nice review of a rather unusual beast (well it is actually a reused "Beutepanzer")... it's kind of funny to make it a re-captured Belgium one, makes it kind of "coming home to the troops"
One thing I noticed, though (and sorry for being a smartass here)is you calling it "ausf." which would be the short term for "Ausführung" (edition or model), whereas it was actually "auf" which means "on" -> "7.5 PAK auf GW" means 7.5 PAK (Panzerabwehrkanone) ON Gefechtswagen (fighting vehicle).
