Nothing stupid here, since we were friends and allies in this war.
I am interested, did Americans and British asked for our most modern tanks, like T-34-85 or IS-2 for same investigations, like was with M26?
I know only about tests with KV-1 and T-34. Even saw the information, that British did have plans for producing T-34 on their factories (!!!), but it never happened. Credits to Crecer13 for this source: https://warspot.ru/13725-tridtsatchyotverka-na-gastrolyah
I am not quite sure of the if Brits continued to "import" soviet AFV after they have decided to follow the US design. However, since the US and the UN forces was doing testings on the T-34/85 they captured in the Korean War, I am guessing they have not received anything but in the early stage of the war.
