some interesting points are raised

Siemens was actually reorganized into the BRAMO company after the war and they went on to produce a number of impressinve engines, including the BMW 801 used in the Focke Wulf
and also the BMW 003 turbojet which was used in the HE 162 and Arado 234
it is not correct to say that Siemens was responsible for the design of those aircraft anymore than it would be correct to say that
Rolls Royce had anything to do with the design of the Spitfire, Lancaster or P51

the plane was certainly a joy to fly by all accounts but there are no accounts of the aircraft ever engaging in combat

regarding the Snipe...certainly far more of them
reached operational status...between four and five hundred before the war's end
the Snipe was operated in combat missions by at least two squadrons and was assigned to several others but too late to see combat
Canadian ace William Barker was flying a Snipe in his famous combat that earned him the Victoria Cross

while it could certainly be argued that neither aircraft had much bearing on the outcome of the war the Siemens definitely comes off as the long shot for inclusion in a counter mix
