[Milsurplus] [ARC5] What is this flex cable for ?

[Hubert Miller]

Not that i come across such flex cable on my own very often, but i think i should learn the characteristics 
of the various sizes:

ARC-5  SCR-274  ARA-ATA  SCR-183/283   RU-GF   RCA-commercial  Bendix MN-series  SCR-269-series   ARN-6  

and archive the information so i'm able to identify what's needed or what a particular  cable can be used with.
