I'm not sure if you're supposed to, or are allowed to mention other sites,
But i came across this upcoming auction whilst looking for a WW1 medal I was after.
There appears to be the sale of a lot of QSA's & KSA's to KOSB(Mainlly) and some other Regiments. The listing i've found is not laid out in order or very well, but i hope it might be of interest to someone.
I'm in no way associated with these people or have bought anything from them, Yet, but I do plan on placing a bid on one or two myself.
