Used Gps Land Surveying Equipment

Where can I get hold of antique surveying equipment?

I am looking for any antique land surveying equipment, as I am thinking of putting a collection together for a display of how surveying started off and how it has evolved to the equipment we use today, like the total stations and gps equipment. I would be looking for arial photos bi-focal viewers, table books, right angles, compasses basically anything unusual or obscure that has to do with surveying, Any donations will be gratefully received. Old rail warehouses, Gov stores etc would be a good place to start but I have no contacts for those kinds of places.
