Yeah, some nice bits on your new ride. Ignition cover is probably for a Lucas RITA. Mick Hemmings inscribed on it is somewhat rare and nice. Think about some air filters, stacks look cool on the carbs, but your piston rings will wear sooner with unfiltered intakes. The crankcase vent to the oil tank from the timing side case is interesting. That was not the norm for a 750. Show us a pic from the left side to see if engine is pre 72 or 73 750. It may be a Combat head, that era motor had a different crankcase vent than what you have. Carbs could be 930 or 932 depending on 750 year.
Note about the fuel tank shutoffs. Depending if proper left-right shutoffs, one would be a reserve. No guarantees. Shut them off when not running. Amal carbs had a bad habit of leaking gas into cylinders and diluting the engine oil. Ride it and smile while enjoying the torquey engine and lack of annoying vibration.

Nice Bike Esben and welcome to the forum.
You will need some type of a air filter. I see one bolt missing at the Caliper Plate.
The the Frame I.D. Plate with the serial number for the bike is attached to the front down tube. Normally this would be on the steering stem tube, behind the head lamp shell. You can see the holes for the rivets have been removed. That Frame Plate should be there. It looks like you got a oil pressure gauge, so make sure your lines that run up to the head and to the gauge is free from touching any parts of the bike. rubbing through the piping with the engine vibration could cause a leak.
Cheers,
Tom

Nice looking bike - is the intake manifold OEM? Maybe it's the photo angle but it looks to me like the standard ham can filter would not fit. And yes, you SHOULD have an air filter though I haven't had one on my Commando for several years! I have long velocity stacks on the Amals and much prefer the bike's response with the stacks. 
As noted, check the fuel taps to see which - if either - is reserve. On my fastback, both taps are identical. What provides the "reserve" is that once the fuel gets down to a certain level, the two sides of the tank are separated. So I use the left side as the normal tap and the right side as the "reserve." There is a bit over 3 liters of fuel in the "reserve" side.
Years ago, on my very first ride home on a 1971 Commando Roadster I had just purchased it sputtered so I switched to reserve - only had 9 miles to go. About 5 miles later it ran out of gas - pushed it about a mile to a gas station.
When I got home I checked the tank capacity and found that the fuel reserve on that bike was about 1 cup (about 240 ml)!!!! So check your tank/reserve capability it to avoid the joy of Norton-pushing!!!
