The G-6 / MW 50 is iirc an early designation for those G-6s carrying MW-50 boost, too. The /R2 bird is a fighter-recce version with cameras and MW-50.

And the G-14, since it had MW-50 as factory production standard, as some ancient paper tells us, is 'wie G-6', but the MW-50 system is using compressed air 'auf Ladeluftbasis'.

the early MW-50 G-6s were usually simple-to-do conversions (only a valve was changed and MW-50 was filled instead of GM-1 afaik) from GM-1 tank carrying high-alt fighters, which used compressed air carried onboard in oxygene bottles, to force GM-1 into the eye of the supercharger. Since GM-1 was a spring fuel used in emergency, it was a simple enough solution, since most fighters didn't carry GM-1.

When the first GM-1 birds were converted to MW-50, they kept that system to force the MW-50 tanks content into the supercharger -
a leftover from the GM-1 system..

The G-14, and later 'proper' MW-50 aircraft were built from the start with MW50 boost in mind, and thus they simply tapped the supercharger's surplus compressed air into the MW-50 tank to do the same - same metod was used for a long time with the droptanks, no need for extra pumps that can go wrong...
