Hi ORKE,
Guten Abend. Wie geht's?...
Thank you for the drawing. It is excellent indeed. Yes it is possible that the change in the insignia was completed in 1976 and it was gazetted only then. Could you please try to draw the insignia for the non-commissioned ranks as well? Thes insignia are almost identical to these used today and also to the ones from the pre-Castro era. I was lucky to find the pre-Castro insignia in an American military handbook from WWII. Unfortunately I did not have the access to the copying machine, so I have only hand-made drawings. I made a description
here.
The insignia you have drawn had been in use until 1980, when they were replaced by new ones, practically identical to Soviet ones, which are depicted at
www.uniforminsignia.org.
I remember during a visit to Leningrad in the summer of 1981, I was sitting on a tram, next to a captain, whom I thought to be a Soviet Army officer. Only upon a second look did I realize that he had a different device on his cap (more peaked than the caps used in the Soviet Army, closer to a German peaked cap). Now I know he was a Cuban captain and the device onhis cap was a Cuban one.
Mit freundlichen Grüßen,
Lukasz
