The Dynamo was the sports organization of the Ministry for State Security and the Police. It was divided into three sizes- the SC (sport club), the SG (Sportgemeinschaft- Sports community), and the SV (Sportvereinigung- Sports association). The SG Dynamo could have several SC Dynamos attached to it while the SV Dynamo could have several SG's and associated SC's attached to it. The SC Dynamo would concentrate on a single sport; the SG's would have a couple to a few sports under the same roof; the SV would have several sports under the same roof. The main Dynamo was SV Dynamo Berlin, and was headed by Erich Mielke- head of the Stasi- from it's inception in 1953 until 1989.
I have a reasonable collection of Dynamo items I thought I'd share. First off, an early bronze honour badge (full size and miniature) and document from 1961.
"We are Marching for the Victory of Communist Labour" V.I. Ulyanov (Lenin)
The next image is the gold honour badge (full size and miniature) to the same individual. The flag of the badge went from the tri-colour to red in 1973; this document is dated 1977. Note Erich Mielke's actual signature here.
"We are Marching for the Victory of Communist Labour" V.I. Ulyanov (Lenin)
The previous documents did not come to me with mappe (document covers); the next two did; the silver in a dark red cloth covered mappe and the gold in a red leatherette mappe.
"We are Marching for the Victory of Communist Labour" V.I. Ulyanov (Lenin)
Next, the full sized gold badge and document, to the same individual, dated 1979. Again, Erich Mielke's hand signature (must have been reserved for gold).
"We are Marching for the Victory of Communist Labour" V.I. Ulyanov (Lenin)
A collection of Dynamo honour badges. The red case is for the full sized gold badge. The badge I'm lacking is the gold badge with tri-colour flag- still looking.
