Ah, looks like you never got an answer on this one. Well, the DJ achievement badge was instituted on the 26th of September 1935 which puts it within the timeframe where the RZM had control but despite this, the badge in your post has no markings whatsoever. I have an early (pre-RZM) HJ achievement badge in silver but as you can see, the manufacturer is shown. That needs to be explained. What do others think?
the lack of any markings is allways a concern but in saying that the badge itself does not look too bad, no casting marks and the pin assembly looks correct
Although this badge was instituted after the RZM was in full control, these badges look fine to me even though they aren't marked as we might expect them to be.
