Silver used to be stored at RAF Quedgeley (you couldn't make that name up!) but Quedgeley closed in 1995. (Not sure if Wroughton pre-dated Quedgeley? Or vice versa) Tracking down what must be a small mountain of old Mess silver would make for an interesting bit of detective work for someone with a few days to spare.
To my mind, it should all be on display somewhere rather than be flogged off. As the RN is fond of reminding us, the RAF is light on traditions and I shudder at the thought of squadron silver being shovelled into a furnace somewhere for the sake of a few quid.
