Socialist Party (Sweden)

The party emerged as a split from the Communist Party of Sweden in 1929. From 1929-1934 it also used the name Communist Party of Sweden. 1934 it unified with a dissident social democratic faction from Göteborg, and took the name Socialistiska Partiet (Socialist Party). It gradually disintegrated, and developed a pro-Nazi position during the war. I've seen the picture of the flag on several black-and-white photos. However, I'm not sure whether the hammer would be white or yellow.
