I hadn't heard about this poem at the Joint Services School for Linguists, Coulsdon, which I attended from 1951 to 1952, but I bought a copy of a 'vest-pocket' edition corresponding to and e's description,at Foyles London bookshop in the early 1960s. It was issued by Flegon Press, the imprint of Alec Flegon, a rogue publisher who was persona non grata to the Soviets.

Alas, I subsequently lent my copy to someone, with the usual result. If anyone's ears are burning, please get in touch so I can retrieve my property. Otherwise let me know where another copy may be obtained.
