of these were only delivered between 3 and 5 May 1938, the next ten between 2 and 3 June. On 27 July 56 had been produced and 34 delivered. The penultimate delivery was on 21 November, the last vehicles were probably produced just before the end of 1938. The second and third batch incorporated the improvements made in 1937 on the first batch but also featured some unique modifications such as a Synchromesh gear box and reinforced chassis girders in the front of the vehicle to ensure a sufficient frame rigidity: a severe distortion had occurred on the earlier vehicles. The AMR 35 vehicles remained very unreliable: on 1 January 1939 only 129 chassis of all subtypes were present in the combat units, the others being centrally repaired or having been sent back to the factory. Due to the structural delays and technical problems it had been decided in 1937 to eventually discontinue AMR 35 production and to supplement the existing vehicles by a more reliable and powerfully armed new armoured car, the AMR Gendron-SOMUA. For Renault, the entire AMR project had been a financial disaster. On 16 November 1938 he begged the government to be exonerated from the contractual fines, pointing out that he had already, on his expense, twice completely replaced the gear wheels on all vehicles and additionally all transmissions and front axles. Variants and projects The three orders of 1935 and 1936 called for a production of two hundred vehicles: eighty-seven of the AVIS-1 version, eighty of the AVIS-2 version; thirteen of the ADF 1; ten of the ZT 2 and ten of the ZT 3. However, the total number of vehicles based on the AMR 35 chassis was higher: there would be ten Renault YSs built; the third AMR 35 prototype used the AMR 35 suspension and finally there would be a production of at least forty of the ZT 4, resulting in a grand total of 251 units directly belonging to the larger AMR 35 family. Also two YS prototypes were modified with the AMR 35 suspension and one of these was again rebuilt as the Renault YS 2 prototype, that is generally considered an AMR 35 variant. Apart from these, three AMR 33s were built with the new suspension, two AMR 33 prototypes were rebuilt with it and about half a dozen AMR 33's were likewise modified in 1940. Also the sixteen Renault
