Soviet Military Truck 5-Speed Shift Pattern & Transfer Case Control Plates (Russian)

This photograph shows two riveted metal instruction plates (data/spec plates) mounted on a painted olive-drab metal panel, apparently inside a Russian/Soviet military vehicle cab. The upper black plate is a gear shift pattern diagram for a 5-speed manual transmission with reverse: ЗХ (reverse) and 1st on the left gate, 2nd and 3rd in the center through Н (neutral), and 5th and 4th on the right gate. The lower plate is a transfer case / driveline control legend in Russian. It covers four controls: the front axle (ПЕРЕДНИЙ МОСТ) with positions ВЫКЛ. (off) and ВКЛЮЧ. (on), warning 'НА ТВЕРДОЙ ДОРОГЕ НЕ ВКЛЮЧАТЬ' (do not engage on hard/paved roads); the demultiplier/range reducer (ДЕМУЛЬТИПЛИК.) with ПОВЫШ. (high), НЕЙТР. (neutral) and ПОНИЖ. (low); the inter-axle differential (МЕЖОС. ДИФФЕР.) with РАЗБЛ. (unlocked) and ЗАБЛ. (locked); and the power take-off (ОТБОР. МОЩН.) with ВКЛЮЧ. (engaged) and ВЫКЛ. (disengaged). A partially visible plate to the left reads ПРОДУВ / ПУСК (purge / start). No make, model, part numbers, or dates are visible.
