United States. War Department, Dictionary of Spoken Russian — §16… (1945)
“ The Р forms of один are used in the meaning "only," "alone." The pronominal adjective сам stresses the identity: я спросил самого полковника "I asked the colonel himself"; it is different from the regular adjective самый "same": я встретил того самого полковника "I met that same colonel." ”
