Rare English Silver-Plated Astrolabe, 19th century, hand engraved and astronomically correct, used by astronomers, navigators and astrologers to locate and predict the positions of the sun, moon, planets and stars, also used for determining local time, local latitude, surveying, triangulating, and to cast horoscope, h. 5-1/4" dia. 3-1/4".

In good overall condition, exhibiting normal rubbing, abrasions and wear. The inner copper dial shows fragmentary evidence of worn silver plate. The ring/handle at the top exhibits wear to its plated surface. The other white metal on the piece does NOT appear to be silver plate, but rather a silver-colored alloy. Letters and numberals appear to be hand-stamped
