There was 391 "Mobelwagen", "Wirbelwind", and "Ostwind" produced - all basically the same vehicle. There were other AA vehicles as well, are they all represented?
One Me262A-1a/U1 had MK103 cannons and flew ONE mission. So why not ask for the Me262(WkN112355) with 6 MK108 cannons as well? Or why not have the Me262 with the 4 MK213 cannons?
Am still waiting for a definate quantity produced for the Fw's /R3. How about some combat records of its use(where, when, who). What 'kills' did it claim.
Your logic means any prototype a/c should be included in AH.
Those MK103 on the Fw could not hit the broad side of the barn door if they were parked right in front of the door. Also the performance of the Fw was drastically reduced with the /R3.
