Here's a link to pics from the last Kempton in December.

Among the huge array of airguns on offer, I can see an original Parabellum with open sights, a Woodstock with open sights, an AR7 with the correct Field front sight but missing the rear, a later Woodstock based on the Hi-Power action and a later AA Hi-Power, which I think came with open sights in a separate bag.

As for an AR7 with singlepoint sight in the correct mounts, I have a story; I mentioned to one of the dealers a few fairs ago that I was after one and he offered me the next one that came up. What a result! It also came with 5 tubs of Jackal pellets.
