Panzer Puzzle

Start: 10/04 - Finished: 16/04 (dd/mm, CET)

Rules New parts are added every 2 days. The first participant (according to recipient's date and time of the e-mail) who sends a correct solution wins. All fields of the form must be filled out / selected halfway exactly! Example: Designation: 'M4A3 Sherman' instead of 'American tank' Each participant may send in only 1 (one!) answer. If you send more than one answer, only the first is valid. No trial & error ;-) Former winners may take part only as unofficial competitors. Former winners: Zerstoerer, Jerry, n.n., Skully, F. Porsche, Jaeger, Marodeur, Maxel. Note: please do not understand 'Panzer Puzzle' literally. It just sounds nice, and actually, in German every tank of every nation is called 'Panzer'. Basically any armored fulltrack vehicle can be subject of this puzzle.

And the winner is ... Gerd, the Portal chief historian (correct guess already after the 1st update)! It is in fact a Semovente (da) 75/18, an Italian assault gun inspired by the German StuG III. 'Semovente' just means 'self-propelled', '75' is the calibre in mm, and '18' the calibre length, i.e. the gun is 18 * 75mm 'long' (even shorter than the German 75/L23 on the early StuG and Pz. IV). You can find the orginal image in its context here and many other Italian AFVs at this great Italian site (look for 'equipaggiamenti' and click the appropriate pics).
Put the mouse cursor on the image to view the entire semovente.
