E188CC identification

Hi everyone,
I just bought a pair of E188CC (gold pin). Usually when I buy NOS tubes locally, I do some research until I find the manufacturer, year of production, etc., based on the inscriptions on the glass. Having exhausted my typical sources of information, I still cannot determine.
The inscriptions (see photographs) are:






Upper rectangle:
Arrow
7501
Lower rectangle:
CV5354
E188CC
Opposite side, with not very legible letters:
GTI (I think)
R2F1
As I understand it, the information enclosed in the upper rectangle means:
Arrow : Government
7501: First week of 1975
Lower rectangle: Type of tube CV5354/E188CC, with military nomenclature.
The information on the opposite side possibly of the factory, but I cannot identify it, for example with the code list of Which Those CV Valves?
by Chris Cooper, nor by looking at hundreds and hundreds of photos on the internet.
Can anyone help?
Thanks in advance.
