I have Kingpin which is 10 as Daniel mentioned, and a great player.

The 15 on Target Alpha as Stangeways said is a great game too - was my second choice if I didn't score KP, and as it's a sci-fi theme would have sat in the collection well too. That layout as you can see was so good they used it quite a few times.

Some great selections there guys thank you very much , as an estimate  what price would an excellent example of these go for ?
He's not keen on one that needs work to be done or one showing wear .He'll fork out the $$ for collectors condition .
