Tirohia te wāhanga i raro nei, kātahi ka whakautu i te pātai i muri mai i te reo kotahi me te wāhanga:  Passage: I muri i te pakanga ka kitea e ratou he waahi hou i Abingdon Road, Kensington ka hangaia he motuka hou. I wehe a Bamford i te tau 1920 a ka whakahoutia a Bamford & Martin me te putea mai i a Count Louis Zborowski. I te tau 1922, i hangaia e Bamford & Martin nga motuka hei whakataetae i te French Grand Prix, i haere tonu ki te whakatakoto i nga rekoata tere me te manawanui o te ao i Brooklands. E toru nga Team Cars mahi me nga miihini cam takirua 16-kikoi i hangaia mo te whakataetae me te pakaru rekoata: te nama anga 1914, i whakawhanakehia i muri mai ko te Green Pea; te nama anga 1915, te motuka rekoata Razor Blade; me te nama anga 1916, i whakawhanakehia i muri mai ko te Halford Motuhake. Tata ki te 55 nga motuka i hangaia mo te hoko i roto i nga whirihoranga e rua; te anga roa me te anga poto. I whakamutua a Bamford & Martin i te tau 1924 ka hokona e Dorothea, Lady Charnwood nana i whakanoho tana tama a John Benson ki te poari. I raru ano a Bamford & Martin i te tau 1925 ana i akiaki a Martin ki te hoko i te kamupene (kua wehe a Bamford). I muri mai i taua tau, ko Bill Renwick, Augustus (Bert) Bertelli me nga kaituku moni tae atu ki a Lady Charnwood i whakahaere i te pakihi. I whakaingoatia e ratou ko Aston Martin Motors ka neke ki nga mahi o mua o Whitehead Aircraft Limited Hanworth i Feltham. I mahi tahi a Renwick raua ko Bertelli mo etahi tau, a kua whakawhanakehia e raua he miihini wha-whatiwhati e wha-whatiwhati e whakamahi ana i te hoahoa o te ruuma wera a Renwick, i whakamatautauria e raua i runga i te anga Enfield-Allday. Ko te motuka anake a "Renwick me Bertelli" i hangaia, i mohiotia ko "Buzzbox" a kei te ora tonu. I whakamahere te tokorua ki te hoko i a raatau miihini ki nga kaihanga motuka, engari i te rongonga kua kore a Aston Martin e whakaputa, ka mohio ka taea e raatau te whakamahi i tona ingoa ki te tiimata ki te whakaputa i tetahi motuka hou.I waenga i te 1926 me te 1937 ko Bertelli te kaiwhakahaere hangarau me te kaihoahoa o nga Aston Martins hou katoa, i mohiotia ko "Nga motuka Bertelli". Kei roto ko te 11⁄2 rita "T- Momo", "International", "Le Mans", "MKII" me tana putunga whakataetae, te "Ulster", me te 2 rita 15/98 me tana putunga whakataetae, te "Speed Model"....  Pātai: He aha te waka i whakamātauria e Renwick rāua ko Bertelli i tō rātau pūkaha whā-whā o runga?
