Help with Markings on British Revolver Ammunition Pouch

[lanners55]

Gentlemen. I wonder if anyone can identify the markings on the back of this ammunition pouch?

I /I\ M over A. Below that is Cd.15

Is this a 1915 date and does the A have RFC ( Air) association?

Best regards,
Simon

Those appear to be typical maker and acceptance marks. Revolver ammo pouches typically would not be unit marked. If it belonged to an officer it was his property as officers had to furnish their own equipment. The only OR (other ranks = enlisted) I know of who were issued revolvers were machine gun crews.

Many thanks for your help. Best regards, Simon
