Hello Tony, Reichsbahn Greetings. Polux

Polux is partly right. The badge looks as the form for "Bautechnischer Aussendienst"
(technical constructions branch in the field organization).
It could be worn by: technischer Reichsbahninspektor, technischer Reichsbahnoberinspektor and Reichsbahnamtmann.
The silvered form was in use with "Klein- und Privatbahn", a golden version was for the "Deutsche Reichsbahn".

I have some problems with the circle. This should be a wheel, according to the regulations and drawings (Dienstkleidungsordnung - DKO).
The pair of compasses is neither okay, as the part should go over right (1924, 1936 and 1939).
After April 1941 they should officially not be worn anymore!
