Luftwaffe Schellenbaum Wünstorf Banner

Hi, Excuse me if this is not relevant to this forum but I am trying to research the history of a flag/banner I have in my possession which was passed on to me by my late Father who passed away a number of years ago.

It has written in silver embroidered letters Fliegerhorstkommandantur Wunstorf, I must admit for years I thought it was Munstorf?

Can anyone help me with any information about what it was used for.
Many Thanks Paul.
