Help

Hi Guys
I have had a nice chappy from BBC Ireland ring up regarding information on a British 2 inch mortar round they have.
It will be included in a documentary and they have most of the details however it has the letters ADC on the fins.
Both them and i do not know what that stands for so here i am.
Can anyone help with the identification of the meaning for ADC?
I am presuming its a manufacturer? Any info would be great.
Many thanks in advance
Matthew
