One L-NAV
One Vario
One GPS-NAV display
Two GPS20

They came with a glider I bought 4 years ago, and were working when removed recently for a panel upgrade. Includes a box of wiring: everything that hooked them into my glider, plus stuff that I've never used. The two guys I bought the glider from each had their own GPS units, that's also why there's colored tape on the boxes and connectors - they'd each plug their own unit in before flying.

I'm pretty sure the GPSs are model GPS20, not the GPS10 or GPS25, based on the description and dimensions in the manual (http://www.bas.uk.net/docs/GPSNAV5.PDF), but I might be wrong about that. I only used one of them, and it's worked fine. The original owners said both worked, but also that they have the "date problem", which is an issue if you want to use them as certified recorders, they work fine for navigation. Search Cambridge L-NAV date problem" if you want more information on that.
