This is not a proto but a small serie vehicle, interesting aniway:
Panzer II ausf L "Luchs"
In late 1941 the HeeresWaffeAmt (HWA) ordered the design of a new 13 tons fast fully tracked vehicle for recoinassance purposes.
It was to be armed with a 37 or 20 mm gun and a machinegun, it should had a powerful radio set with "sternantenne" in order to comunicate with platoon commanders and artillery batteries up to 35 km.
3 proposal were submitted in june 1942, one from Skoda, other form MAN, and the later by Saurer.
After intensive testing the Man proposal was declared as the winner in june 1942, eventually 300 vehicle were ordered but later this order was reduced to 100 tanks.
