We bought it about 10 years ago, it came in a lot with some scientific items (microscope, slides, books) that all belonged to the same man. It's a Thornton-Pickard Ensign folding view camera for 4" x 3 1/4" glass plates. Symmetrical F8 lens. There is a leather lenscap and handle, 2 mahogany slide carriers, 22" - 53" tripod with brass fittings, tin darkroom lamp with a red bulb and some glass plates. There is some other stuff for it too, but it's packed in the bottom of a cabinet and I could not get to it :er: It's circa 1895, the darkroom lamp was refitted for the electric light but it has an oil reservoir at the bottom and you can see where the original burner element was removed.
