APX indicated on 6 April 1936 — the plan to build just a single prototype already having been discarded when the second order was placed — that it desired to have five vehicles ready for the September manoeuvres of 1936. That was a very optimistic assessment, especially given the fact they themselves had not yet sent the superstructure blueprints to Renault. On 26 October Schneider announced that the five empty hulls could not be delivered before the end of April 1937 — the blueprints had not yet been received. On 27 October 1937 — the hulls at Schneider are nearing completion — APX demanded that between 15 and 20 November a "prototype" (not the original one of 1935) would be provided for acceptance. On 26 April 1938 APX approved the hull but only informed Schneider of this on 5 May.
