I'll stick the embarkation roll here:
http://www.fusilier.co.uk/military/7...tion_roll.html
lots of locals in there.
no numbers, but with care you could get them from the medal index cards, these men will have a theatre arrival date of 20/4/15 or 21/4/15, and most will have a regimental number prefixed by 7, like '7/1945' for example. Risk of error? = Yes the other territorial battalions of Northumberland Fusiliers will have the same arrival date, but the numbers might help eliminate them.
