Le Merveilleux c1888
J. Lancaster & Son, Birmingham, England.
Le Merveilleux was Lancaster's lowest priced and most simple model.
Made of mahogany with brass fittings. It was offered in sizes from 1/4
plate (shown here) up to 12x10" and made c1882-1905. This is the 1888
Patent Model. The brass lens is mounted in a sliding tube for fine
focusing. No shutter is present, but a qualified guess is that the rotating lens
cover was used as a shutter.
