Many thanks for your reply Kari. Unfortunately I can't help you with Stkz nor WNr while all my info was from Luftwaffe in Finnland and a few discussions with Kjetil Åkra.
With your elaboration you have explained the defensive armament though, as I was wondering why it was present in that picture. I'm not doubting he flew with guns on board when in Finland but with the courier agreement with Sweden I was a bit curious why the guns were in place if he just came from Norway.
Actually I doubt the guns were removed even if flying over Sweden. Several Kurier crashes saw guns stowed in the airframe apparently.
