I've recently purchased a 6" x 15" camera with book style double dark slide holder for glass plates; can I ask if john was successful in getting hold of additional dark slides?
The camera I have looks to be mahogany with brass inserts and chrome fittings but with no manufactures name. The dark slide fits the back of the camera by lifting the GG back, inserting the bottom of the slide in a grove and then there are two wooden tabs at the top which slot into the top, the whole slide is pushed across to locate the slide.
