You are buying all four slides. These mahogany and brass double dark slides are in "as found" condition. These are a 'harlequin' set. There are no cracks or splits to the wood that I can find and the brass work is in working order, but there is loss of lacquering and tarnishing in places. One of the slides has numbered celluloid inserts. They all open and close as they should. They measure externally 6 inches by 8 inches approximately. The wood has gained a good depth of colour and patina over the years However, they do have scuffs, knocks, stains and scratches that you would associate with items of this age. I have tried to show the condition in the photographs. Please be aware that customs or import duties may apply.
