Pictures would be nice Charlie. I would say in excess of £450 for rifle only. I have known Venom gear sell for a lot more. It depends on the buyer and how much they want it. Try for a valuation on the airgun BBS, as there are a lot of Venom collectors over there.
I would be interested if the price was right.
