What is GAVO and what is the Josefstal Fond? GAVO is the Russian acronym for the Volgograd State Archive in Russia. A Fond is a Russian word for a File series.
In this case, Fond 270 is the Josefstal Fond. Originally part of the archives in Engels, the Josefstal Fond was moved to the State archives in Volgograd, probably in the 1960’s.
It is a Fond I have been privileged to consult extensively. I am putting the Russian version up here for those who might be interested.
And here is the English translation. Enjoy!
