There were a couple a few years ago. One in Milton Keynes I believe. I can't remember who organised that one, but there may be pictures on RWG1. There was a small one in Holborn just after that and the likes of V, Exper, Finepics, Kasigi (who hasn't been around for a while?), were there. There may still be pictures around. I remember taking my RXW Plasmir Milgraph there, and V had his 212 back then with the Hirsch Trieste deployant strap, relumed by finepics, and finepics with his beloved PAM127 ... those were the days
Apologies to anyone I didn't list, my memory is hazy, and I got there a while later than everyone else, so may have missed a few.
