In 1895 J.H. Steward produced a Verner patented compasss, which was a pocket compass and not a prismatic compass. (You can find the prismatic Verner compasses next to this one) It has distinctive compass card markings. ( foto 2) The card design is the one of the Royal Geographical Society (R.G.S.): the NORTH direction (black diamond) could easily be distinguished in the dark, because the background glowed greenish blue. When this compass was produced, "glow-in-the-dark" paint was added on the compass dial and to the lid. Phosphorescent paint is commonly called "glow-in-the-dark" paint. It is made from phosphors such as silver-activated zinc sulfide and typically glows a pale green to greenish blue color. The mechanism for producing light is similar to that of fluorescent paint, but the emission of visible light persists for some time after it has been exposed to light.
On the bottom a name is engraved, but it is partly removed.
