Loughran dates I244 to 1941–47; Mitchell gives the same period for the I247 funnel.
I245’s funnel is supported by a photograph of Irish Oak around 1965. The source labels a National Maritime Museum flag I245, dates it after 1947 and records dimensions of 889 by 1828.8 mm.
The original flag had company initials in its quarters, replaced in 1947 by the arms of the four provinces. I246 follows the National Maritime Museum, with shields also illustrated by Loughran, who gives flag dimensions of six by three feet.
