B. R. Copper signalling lantern…
A good example of this type of piece. All parts stamped B.R. made by Bladon of Birmingham. The original internal paraffin burner has a shaped porcelain wick holder. The handle is attached to the internal sleeve which, when spring loaded released, rotates to change the glass colour window from clear, to red to green. Added to all this is a complete bevelled glass lens!
A bargain at £75!
