NJG 1
 

Hi guys, hope someone can help with the following

I have in my collection a mapcase which has a name and unit written inside, it reads as follows

Hofmann
1.st. 1. NJ. Geschw
Berlin

i assu e this means 1st staffel of NGJ 1 but i am confused about the berlin bit. From the info i have been able to find on the net, this unit was at Venlo in Holland

can anyone shed any light onto this person or could it be just made up
