Russian to English Social Sciences History references to archives

I'm translating a document that quotes several archival documents. At the end of each passage, there is a reference similar to the one above. I've figured out what all the abbreviations mean, but I'm not sure what would be the best way to translate the references. I think writing out all the words in full, while it would convey the meaning, would be rather awkward. Other options could be to transliterate the Cyrillic abbreviations, or to translate the words for which the abbreviations stand and make abbreviations from them. Or I could just leave them in Cyrillic. The point of such references, of course, is to help the reader find the original documents if need be; what method of rendering would then be most appropriate? And does anyone know if there are analogous abbreviations in English, and if so, what they are?
