Most interesting marking.
The concern of Robert Thiel from Danzig must have lost its permission or never had gotten one
from the Reichszeugmeisterei in or about 1934. This concern was not listed at all in the 1935
"Handbuch der Reichszeugmeisterei". So, when the handbook was started they had no
such permission, but have manufactured anyway buckles for the SA, DJ or HJ in about late 1933.
Later they got the permission M4/112. This possibly must have come into being after Danzig came
into the Reich when WWII started. They then may have asked for an RZM-permission. Got it, but
lost it already per April 7, 1941. They were not allowed to produce buckles anymore.
The reason was not mentioned in the "Mitteilungsblatt der RZM", nr. 7 from May 10, 1941.
