German MK 101Z mid-air refuelling system?

[Pioneer]

G’day gents

Currently flicking through.Luftwaffe over America: The secret plans to bomb the United States in WWII, by Manfred Griehl.

In it, he states that the Luftwaffe had a mid-air refuelling system called the MK 101Z device. Does anyone have any details of this MK 101Z?
In the book, it states that the Luftwaffe tested the mid-air refuelling concept between a Junkers Ju 90 and a Ju 290 (if my memory serves me right)
Although the book alludes to the Luftwaffe favouring a Heinkel He 177 to He 177 concept.

Thank’s in advance!

I guess Im right out of luck with the MK 101Z system then :-\

So does anyone have any picture of any German mid-air refuelling trials that were conducted by the Luftwaffe during WWII?
