I suppose, it is not a firm, but a school ("technicum") in the city of
Yoshkar-Ola (Russia).
I think, that the "FGOU SPO MRMT" is the same as "FGOUSPO MRMT" and "ФГОУ СПО МРМТ" and means:
(in Russian)Федеральное
государственное
образовательное
учреждение
среднего
профессионального
образования "
Марийский
радио
механический
техникум"
(in Romanized Russian)Fyedyeral'noye
gosudarstvyennoye
obrazovatyel'noye
uchryezhdyeniye
sryednyego
profyessional'nogo
obrazovaniya "
Mariyskiy
radio
myekhanichyeskiy
tyekhnikum"
(in English, literally)The Federal State/Public Educational Institution of Secondary Vocational Training and Education
"The Mari Techical Secondary School of Radio Mechanics/Engineering"Here its site (in Russian only):
http://mrmt.mari.ru/The "ФГОУ СПО" ("FGOU SPO") is a generally used abbreviation in Russia.
Actually, the "MRMT" also could be the short name of any technicum of Radio Engineering, which town's name or the state name starts from the "M":
M...('s)
Radio
Mechanic
Technicum. However, I have not found on the Internet any information about another active "MRMT".
