A bit of information about this Armoured Machine Gun Car: this Armoured Train Casemate Wagon component was used to make any of the 10 Austro-Hungarian Type B PZ Armoured trains that began to see service from 1914 through to the end of WWI. They saw service on all the fronts where the Austro Hungarian Armies fought.
After WWI the surviving trains went to Yugoslavia, Poland, Hungary and Czechoslovakia. After WWII commenced, Hungary used its trains, and those of Poland, Yugoslavia and Czechoslovakia fell into German hands.
Panzerzug 24 was created from these captured trains and saw service from March 1940 to January 1945. It served in Germany, briefly in Denmark, also in Serbia, Croatia, Italy, France, & Poland However it underwent many upgrades during the WWII and the Hunor pieces are good for 1914 up till mid 1940. In January 1945 along with Panzerzug 62 (a BP 42 type),the trains were cut off by the Russians and the crews blew the trains up around 07.45h on January 16, and accompanied by their 38(t) tanks the crew marched off to regain their own lines, harrassed constantly by Russian air attacks. However by 1945 Panzerzug 24 no longer resembled the Hunor train pieces, having been upgraded with replacement stock and larger locomotives.
