Anyone ever hear of this Soviet freighter? (It was one of the disguises used by the German commerce raider Pinguin). Wondering if someone knows what its paint scheme was - or that of any Soviet freighter in WW2.

Hi Doug,
Here is some reading which claims that Schiff 33(Pinguin) disguised as the Petschura, had a black hull
and wore hammer and sickle markings.

Hope this helps,
