Hi Cardo,
check with local vehicle (military ) clubs in your area, depending on what has been removed from the engine (it appears to be all there), first of all do the basics, battery (can remain 6 volt) fuel, spark will engine fire up ?
Timing to check, check fuel lines for debris check all oil levels in engine,gearbox,transferbox, axels.(the area of the manuel that explains on using the vehicle for the first time)
If successfull and engine runs....... bleed brakes drive it (on private land)
There have been some post war modifications (indicators) when reading the manuel look for the data plates (glove box) chassis rails to assertain the age of the vehicle, engine and chassis numbers.
This looks like a great vehicle good luck with it and enjoy.
