The National Library's map section has a light table surplus to requirements 1.5x1m tabletop, 1m tall. Wooden framed, and tiltable to ease of use (or storage), on metal legs. The legs removable, so can be transported in a station wagon.
1970s vintage but electrics tested and tagged this year, and in perfect running order.
Needs to be picked up from the National Library. If interested, contact me to arrange pickup (ideally this week, but negotiable).
