“During the war two small companies, Stinson and Argee, started "pirating" Soviet records mainly for the Russian-American market. Surmach encouraged them to issue Ukrainian records, too, and subsequently started doing the same, encouraged by their success. As the Soviet Union had not signed the international copyright convention, there were no legal problems.

Surmach issued about eighty 78s on his Surma, Fortuna and Bayan labels. Only a handful were recorded in the USA; among these, the epic duma songs of Zinoviy Shtokalko deserve special mention.

Some of the records were custom pressed by RCA, some by a company on Long Island. The latter charged 18£ per disc, including the cost of preparing the pressing matrices from the original Soviet discs.”

Note: The only discography I've been able to confirm for 1940 is Eric Bernay's Keynote: Music Room International Series. Everybody else, it seems, was keeping a very low profile during the FBI's pre-war round-ups.
