To set the ball rolling, when RLM started to gear up for the war and combined with the Industry constantly building each others aircraft under licence it soon became obvious that sooner or later they would face the problem that various manufacturers used the same WNr for the same type of aircraft.

The WNr you quote has to be placed into each manufacturer's range, meaning WNr 2789 etc was in the Messerschmitt range and 2941 etc was in Arado's range. You cannot mix the two ranges together.

In the end RLM took over completely and assigned WNr centrally to the various factories to overcome this problem.

Question 1: Not home so cannot check
Question 2: Initially (before RLM took over) Messerschmitt used their own range and the Bf 108 was included in that range
Question 3: Not home so cannot check, but just because a new model appears, it is not always necessary that an older model is stopped immediately.

Cheers
