Yusom, thank you very much for your help!
I have seen now the Red Guard Odessa badge on a webpage: http://www.russian-medals.net/pics/nysa ... 60_198.pdf
Revolutionary Badges: page 3, no. 2387/ Description
: The Red Guard of the Social-Democrats (Bolsheviks) of the city of Odessa. 1917. 50th Years Anniversary Badge. 1967. White metal. Red light enamel. Was given to
survived veterans of Revolutionary and Civil War events in Odessa district. Screwback 1967???
I dont think my badge is from 1967. The backside of the item seems not to be after WW2. Also the screwplate. I am right?
I have another question. The badge from 1931, "Six conditions of Comrade Stalin"
. Is this the official name for the badge? Cant find any in the net but on the webpage above I have found a similar item (no. 2424), named "To a Shock Worker of 1932. Completing of Five-Year Plan". I am irritated.
Best wishes from Germany!
