This lantern has a Russian iron lamp house with fretwork, two side opening doors with peepholes, a rear stable type door, and a cowl which does a good job of blocking extraneous light. The front end is all brass with a triple extension, spring loaded changer mount, and good rack & pinion focussing via an excellent combination of 4 inch condenser and objective assembly. Inside is a sled carrying a parabolic reflector, and a lampholder with 250 watt projector bulb and cloth covered cables to a bayonet plug for the UK lighting system. The sled carries a label for W.Butcher & Sons. It measures 47 x 29 x 17 cm and weighs 10.8 kg.
