ME 109g-6 u4 arnaments?

[Kurfürst]

It may be that examples special purpose planes found their way into 'ordinary' fighter units, and were issued if nothing else available, and in the end not used for their original purpose.

Take the well-known G-6/U2 that mis-landed in the UK in July 1944; originally it was GM-1 carrying high altitude fighter (/U2); the pictures also show the small bulge for the pressurized compressor on the right side, so it started it's carrier as a special purpose, pressurized G-5 with GM-1 boost - it ended up with JG 300 (or 301?) chasing bombers under the moonlight, without any sort of special equipment present.. I am sure life produced plenty of such 'misuse' of equipment.
