Its not marked ,and lugs north and south.
Besides Peter's example i only know of one other.

Sheffield UTC is missing.
Bham OTC in silver too,but it was supposedly worn by security staff. Whether that is just a myth i dont know.
I will check my records later and check against known examples. Theres a few that possibly existed but nobody seems to have produced an example .

I forgot the WRAC for up to 1991 female UOTC OCdts wore the a/a WRAC badge.

From the late 1980s most of the Southampton UOTC female cadets actually wore the officers No1 dress WRAC badge in s/g on their berets; that was due to the fact that Tim the NRPS storeman had mistakenly entered the wrong NSN!

Ive checked and as Alan said previously Cardiff pre the dragon and Southampton pre the re-introduction of the shield badge.
This one isn't there,ive never seen one. But somebody must have one as I have an image.
Also the large Liverpool UOTC.
Btw the badge is not mine.

Hi William,

Some pretty rare items on show!

I have a feeling that you now have probably the most complete collection of A/A cap badges out there!
