I've been trying to get hold of SO2 Heritage at Air Command (High Wycombe) for a while. This person looks after such items- I was hoping to draw some for representational purposes in my overseas post (there, I've inherited and signed for, an eclectic selection of RN silverware including a silver Dreadnought. I don't know where RAF items are stored, last I heard about it, it was at Stafford.
When I'm next back, I might pop up to High Wycombe and try and track down this person; I have a feeling that this post is gapped.
