Thanks to Chris and to MikeH for the Rarities Lists; I suspect you covered almost everyone's Agonised Ally Wish Lists between you.
Although they are probably prototypes or trial badges I offer these for general thoughts and comments from the forum, as I understand there is at least one each of these v rare AA cap-badges out there, already in members' collections:
- Derbyshire Yeomanry - Gold & Silver QC
- 1st Rifle Volunteers Royal Devon Yeomanry - Gold & Silver QC
- South Staffords - Gold & Silver KC
All the best
William
