I want it!!!

Oh mate that is wicked. Imagine the fun you could have with that!

I'd soon clear out some of the chavs from the estate!

Can't we raise the funds between us???
If you have aspirations to overthrow a neighbour’s castle, the ballista isn’t ideal, as even though it is potentially capable of throwing a stone ball over 100 yards, it is now not in firing condition. (Please note that even if it were, you would need a team of several skilled operators in order to do this, and these are very hard to find today. You may also find that advances in weaponry since this was designed place you at a considerable disadvantage on the modern battlefield.)

The ballista weighs approx 12 tons so postage or even buyer collection is not an option

I wouldn't pay 25 pence for that, he's having a laugh at £25k.
