The Jagdpanther was a tank destroyer built by Nazi Germany during World War II based on the chassis of the Panther tank. It entered service late in the war and saw service on the Eastern and Western fronts. Many military historians consider the Jagdpanther to be one of the best tank destroyers of the war due to the combination of the very powerful 8.8 cm KwK 43 cannon and the characteristically excellent armor and suspension of the Panther chassis.
This Jagdpanther was on display at the Imperial War Museum Duxford.
I have a 15mm Flames of War version on the workbench.
