I am not sure this would classify as enough to be a suggestion as there is no hard mounting into the car as far as the picture shows. But its a cool concept anyway.
“Mounting” a Akan m/40 on a AT Tripod at the Back of a Tgb m/39 Gave the Weapon a more mobile element. What the exact use or tactic behind this is not known but one can asume it let the vehicle Act as a Makeshift Tank hunter / Reconnaissance vehicle.(Or it was simply a way to transport the weapon place to place, But i have a hard time believing this as the rear of the car was slightly modified to allow the weapon to be set up firing ready.)
Weapon being just a simple Akan m/40 in a tripod mount for use against ground targets. Its the same weapon used in the Pvlvv m/42 Ammunition and characteristics is exactly the same. Albeit more limited firing arc to the rear of the car.
