Help to correctly identify Тhornycroft

[Konstantin Chernov]

1) Thornycroft EE/SC6 'Special' (IWM).
2) Thornycroft Speedy (Thornycroft Military Vehicles). This car differs from the previous one by its single rear axle wheels and license plate.
3) Thornycroft Speedy (Vanderveen's Handbook, 1974 edition).This truck has a different radiator mask.
4,5) Civil Thornycroft Speedy.
There is some confusion in the model designations. Photos 3, 4 and 5 are late model Speedys. They should be designated EE/SC6. The trucks in the first two photos are probably A12/ OC4 . I could only find two vehicles with these designations in the Thornycroft vehicle registers, both acquired by the War Office. One A12/OC4 (Сhassis) 18. 2. 1931 and one EE/SC6 (Lorry) 22. 09. 1933.
