This is a rare NSB / WA memberbadge.
Most people call this a strictly WA badge, but this is not correct. In fact it was a new introduced NSB badge in 1938, but after a lot of complaints by early members it was withdrawn again and the former better known NSB triangle with lion in the centre remained the sole NSB memberbadge. Many WA members did wear these “new” badges though and they were also displayed on the WA passes.
On the back under the pin maker marked with the logo of maker Friedrich Hoffstätter from Bonn.
In good condition and very hard to find!
