I’m not War Park, but I’ll give you my two cents on the historic info. Like Pauck pointed out above, the paint scheme/markings are a faithful recreation of the Deutsches Panzermusuem Munster’s Hummel. While they paint their museum tanks better than most, they’re usually not sticklers for perfect historic accuracy, and I’m skeptical it was based on an actual historic Hummel. In my opinion it’s their take on a camo Hummel.
The model itself is an early production Hummel, noted by the single armored hull bulge over the drivers position. The later production Hummels had an enlarged rectangular driver/radio operators compartment. For the paint job, it’s an interpretation of ambush camo, which was a factory paint job, but it’s on an early production Hummel that would have been sent to the troops in solid Dunkelgelb and the camo applied in the field. I’ve seen pics of Hummels and Nashorns with factory applied disc ambush camo, but never the small dots found on Daimler Benz Panthers.
Paint job looks nice though, so I’d just call it a generic Hummel, where the troops in the field decided to put some small camo dot splotches on it. It would work as a Hummel from 1943 until the end of the war on either the East or West Fronts, so it’s a pretty versatile model.
