In 1916 the Artillery Brigades of Territorial Divisions were redesignated in the sequence of the numbering of the divisons (42 ... 69). All got roman numerals starting from CCX (210). Not all numbers were used and the result was that the four brigades in a division had their numbers ending in nil, one, two and three I (CC..., CC...I, CC...II and CC...III).
The first column has the original designation and shows the pre-war title augmented with the 1/ or 2/ prefix which were the result of the doubling of the TF. The last column shows the new designation and in between is an arab numerical presentation of it for ease of understanding.
