Every now and then a really rare airgun crops up in a sale and goes unrecognised, meaning that the observant collector has the chance to pick up something very special at a knock-down price. I spotted one such gun on the current Saleroom website, under air pistols (http://www.the-saleroom.com/en-gb/se...Term=startDate ). So here's a question for you - can anyone spot the rarity? If no one else finds it, all will be revealed well before the auction date so that anyone interested can put in a bid.
