Granted but it's a very minor part of the whole design and rather different to the cap badges. I still can't find a link to the cadet corps although clealry Bute had many links to Cardiff. If anyone can provide any source other than Rawlins pamphlet then I would love to see it. I do wonder if the specific Wyvern design is Police or Corporation?

Melingriffith Cadet Corps does not feature as an independent unit in the 1918 Army list

They certainly existed: as the post war merger of the band evidences but they are not listed as part of the Monmouth Cadet Battalions in The Territorials, 1908–1914: A Guide for Military and Family Historians by Ray Westlake.
The 1918 Army List shows that the Monmouths had their 4 CB but did not have affiliations to any independent schools or uniyts.
I do wonder if the cadets who went on to merge with the band were Boys Brigade.
