Workers at a work place were divided in workers brigades. Some big factory could have more than 100 brigades. The most productive brigades were awarded with these pins.
The organisation instilled socialist politics into its members such as working hard to build a better future for all fellow socialists and the idea of an extended friendship towards other like minded individuals
The socialist workers brigade started in 1959, these pin are from the 1960’s.
There were 4 classes of pins: gold, silver, green and bronze.
