Note: On almost every one of these slide rules you will see something like: ГOST5151-57. ГOST translates into the letters GOST which is an abbreviation of ГOCYДPCTBEHHЦЙ or GOVERNMENT which we abbreviate as GOVT. ГOST5161-49, ГOST5161-57, and ГOST5161-72 were the Soviet Standards (like the United States MIL-STD or ANSI standards) which dictated identical design of the scales for all factory locations. The dash numbers -49, -57 and -72 were the years that the standard was revised. The year (r.) built, noted as 1971r., will always be greater than the GOST standard on the slide rule. Another Soviet era standard that appeared in 1972 on some injection molded plastic stock slide rules is: ТУ(TU) 25.01.610-72. Note: the terms LSLD and LSLO mean the type of slide rule construction, LSLD=Duplex and LSLO=Open (or simplex). For reference, Ramenskoye was the centre of the Russian instrument making, in the same place experimental test airdrome "Ramenskoye" (space, military aircraft) was located.

REF Leib Stern Compressor Slide Rule

Leib Stern Compressor Slide Rule - c1957
Made in USSR by LFAI, Leningrad

Designed by Leib (Leonid) Stern. Leib was born in the Ukraine in 1914, and had a long career as a metallurgical engineer in the USSR. He immigrated to Israel in 1987, and had passed away here in 1999. He had the knack for innovation that marks the best engineers, and during his days as a metallurgist he had patented many inventions, including the slide rule shown above.
Archive - Donated to the Nathan Zeldes Collection in Isreal by Leib's daughter.
