With everything being done on the "hubba-hubba", to get the Sovs needed material, no doubt much was sent as-is. Keep in mind that there were likely quite a few in the massive Red Army system who would read/speak English. There were also liasons stationed in the USSR, just to instruct on new systems.
Thompsons were included in the gear aboard lend-lease US tanks, if I remember corrrectly. Factory workers also used to pack some decent chow, cigarettes, and whiskey in compartments and even the gun breach - a gift to their new allies.
