I'd like to own a nice complete Euro set of Vectrex games.
I already have most of them but I'm looking to refine my collection with boxes in nicer shape and unscratched overlays.
Here are the parts I'm looking for (in good condition):
Star Ship 
Box + Overlay
Space Wars Box + Overlay
Web Warp Box + Overlay
Fortress of Narzod Box + Overlay
Hyper Chase Box + Overlay + Manual
Soccer Football Box + Overlay
Pinball Box + Overlay
Spike Box + Overlay + Manual
I don't have the light pen nor the 3D imager but maybe one day...
Of course if you have a complete
Polar Rescue,
Pole Position or
Star Castle, I'd also be interested
Here's what I have for trade:
