Bruce bought the unused jagdpanther hull plates found in a factory oil pit in Germany. The damage to the panther is post French service, when it was on a range
yes it is the Cadman one, it originally came from france, hence no serial number except an AMX one from its rebuild.
From the list of surviving Panthers, the Cadmans only had one Panther and the Cadmans still have their Bergepanther
