I would be very interested to know what year you picked up the pins from Christmas Cove caravan park.
it was in 1994 that i bought the Buck Rogers (along with an empty Charlies angels cab, that i built Vortex from), and about 1995 that i got Solar Ride from Christmas Cove caravan park, along with a heap of Stern Dracula parts (everything except cab and backglass), and a Six million dollar man backglass which ended up getting broken.. and it was a near perfect glass too
One of my mates father lived there (at the caravan park), and last i heard of that place from him was that all of the games are now long gone.
