a weapon had already become obsolete for this role in 1936. The gun had an ammunition stock of 1220 rounds: 740 in 37 magazines of twenty and another 480 in cardboard boxes. ZT 2 The Renault ZT 2 was a tank with a larger octagonal welded steel Atelier de Construction de Puteaux (APX) 5 turret equipped with a shortened 25 mm SARF gun, which had a penetration of forty millimetres at five hundred metres. Despite the name, which reflects that it had been designed by the Atelier de Puteaux forge, the one-man turret, with a weight of 650 kilogrammes, was fabricated by the Atelier de Rueil (ARL), an APX offshoot based at Rueil. It had also been intended to equip the AM 39 armoured car (the Gendron-SOMUA). and the colonial version of the Panhard 178, but apart from the ten ZT 2 vehicles was only fitted to five Panhards, so the planned production of at least 259 remained limited to fifteen. The plan to produce a ZT 2 was first conceived in June 1935. On 12 December 1935 Renault had been ordered to produce a ZT 2 prototype, on a chassis to be taken from the first order of a hundred, but this was annulled when the ZT 2 was made part of the second order in a number of five. On 27 October 1937 the Renault factory estimated that all ten ZT 2s could be produced simultaneous to the second order production run and on 14 January 1938 it was thought that ZT 2 production could be ended in June 1938. Perhaps this was indeed accomplished as regards the first series of five, N° 95860 - 95864. The last five, N° M 3031 - M 3035, would only be assembled in December 1938. This just pertained to the hulls: none of these had yet been fitted with a turret. A first wooden mock-up of one, had been delivered on 13 July 1938. Only at the end of 1939 enough funds were made available to produce the turrets and finish the tanks at Rueil, a process that probably extended well into 1940. The hull of the ZT 2 was largely identical to that of the "ZT 1". Apart from the 25 mm gun, having a stock of fifty rounds, the turret was fitted with a 7.5 mm machine gun, with 2250 rounds. The turret had both a large roof hatch
