One commercial post I think should be fair game on PPrune.
Just spotted whilst deciding what this year's contribution to the Poppy Appeal would be spent on (so, tell me off, I'd rather buy one of the nice things from British Legion to wear than a succession of plastic poppies that I'll keep losing).
Poppy Shop Battle of Britain Spitfire Poppy Pin
A poppy lapel badge, made from duralumin from a spitfire which saw service in the BoB, all proceeds to the British Legion. Beautiful, and more so knowing where it's from. Matching cufflinks also available, if you're one of the 1 in 1000 people left in Britain who ever wear them.
