Panel analog 85C1 GB776-76 DC Ammeter 0-10A rare version of 1990

Spesific analog ammeter 85C1 GB776-76, this is a find in the Greek market which I did touch at 1995.
Originally this was in use at DIY box as VA tester with banana inputs (along an 30V meter).
Now I will reuse it at a new project.


Technical:
85C1 this is reference to product design and shape.

GB776-76 this is code specification, that I am unable to find exact information anywhere.
I can only think code misspelling error? or unique description ?

I think of Kiriakos 1990 find, as genuine 
scale printing it is good but not excellent, printing technology was not that mature back then, in Asia.

In contrast to the other and much older German ammeter (1969) that is spotless.
