Added N°49 item of the ALTAYA/IXO "1/43 WW2 Main Battletanks" series - Waffenträger Grille 17h auf Geschützwagen Tiger II für 17cm K72 (Sf) prototype in blueprint ordnance. It never saw achievement and was discovered as half mounted state. Germany 1945.
"The Geschützwagen Tiger was a German self-propelled gun of World War II that never saw service. The decision to build this heavy artillery based on the chassis of the Tiger II came in June 1942. The first prototype was tested at the end of the war. However, due to Germany being on the brink of surrender, the vehicle never saw service, and was captured by the Allies. While several armaments were considered, the most practical guns to be mounted were the 17 cm Kanone 18, or the 21 cm Mörser 18." (Wikipédia)
