"Festungpanzer III" - Name of that is my idea. It's another unknown type of German late war modification, but great photo is available. You can see that "thing" on the left of ruined street. My kit was based on Gunze Sangyo's Panzer III Ausf. M/N and spare parts of newest Dragon's StuG III Ausf. F-8. Also I used Magic Tracks - winterketten type, seen on that photo. Probably that vehicle was painted with some camouflage sheme ( darker and bright scheme on front plate ). About armament: Front barrel it may be one of Flak 30 or 38. Mounted inside that "bunker" construction. One thing is sure : great theme for model kit :)
