University of Yerevan has a copy (http://89.249.207.20/cgi-bin/koha/opac-detail.pl?biblionumber=156826&query_desc=kw%2Cwrdl%3A%20%D0%A1%D0%BE%D0%B2%D0%B5%D1%89%D0%B0%D0%BD%D0%B8%D1%8F%20%D0%BF%D0%BE%20%D1%82%D0%B5%D0%BE%D1%80.%20%D0%B2%D0%B5%D1%80%D0%BE%D1%8F%D1%82%D0%BD.%20%D0%B8%20%D0%BC%D0%B0%D1%82%D0%B5%D0%BC.%20%D1%81%D1%82%D0%B0%D1%82), and you can obtain a copy from them for a fee.
