1. Photo ID #6 issued by the NKVD of the North Ossetian Autonomous Republic, marked "Valid until 3 March 1943. The photo shows Kozlinkin wearing a Badge of Distinguished NKVD Employee on an M-1943 gimnasterka with distinctive 6- sided shoulder boards (unlike the Soviet army officers who had converted from 5- to 6-sided shoulder boards only in 1946-47, the NKVD used the 6-sided model starting from 1943). The opposite page shows Kozlinkin's rank and position, a section chief. The same page is hand-signed by People's Commissar for Internal Affairs of the North Ossetia. The document is in excellent condition: perfectly clean and sound, and showing only very minimal wear to the cover.

2. Free Railway Transportation Pass, issued on 20 February 1941. Shows that Kozlikin is an officer of the Transportation Department of the Ordzhonikidze Railroad, and that he is allowed unlimited free travel with high level accommodations (in a so-called "soft" car) on all branches of this railroad. Marked "valid until 31 December 1941". In excellent condition.
