Great Britain and England Titles

TITLES

I have 2 titles as shown but I am wondering what they would be for, my thoughts:
Great Britain -The colours are akin to the colours of the International War Graves Commission (IWGC), but I can find no reference to this title being used. Anyone working for the IWGC would wear this or similar titles regardless of country!
England - This is white on black affixed to a tropical, drill epaulette loop. First thoughts are RAF but would expect title to be on blue/grey or similar and why use the word 'England'?
I am a dealer but would like to get things right. I hate putting 'NK' or 'Unknown' on items so any help would be appreciated.
Please don't assume I have all the books/references you may have or that I am able to use them as I have MS and my hands don't work very well.
