Code BA366: ANTIQUE EQUINOCTIAL SUNDIAL COMPASS 1865 IN WOODEN BOX by LABOUP circa 1865
This is an extremely rare French equinoctial sundial compass made around 1865 by Juan Laboup. It comes in its original wooden box and is in full working order. The compass case is solid brass and is quite heavy. The dial is made of a white silvered metal. It has French cardinal points and very nice decorations including two arrows. Above the dial there is a second chapter ring dial graduated in degrees and numbered every 10 degrees. The dial is covered with a glass crystal in excellent condition without chips or scratches. The compass can be used with a latitude bar and folding gnomon bar to read the solar time. There are also two bubble levels and three levelling screws to reach maximum precision. The compass is precise and points North without any problem. The needle can be blocked by acting on the transit lock on the side to prevent wear to the pivot when the compass is stored inside the wooden box. The needle is blue and silver. In front of the dial is stamped the name of the maker Juan Laboup and around the dial there are inscriptions to help read solar time in different cities: Paris 49, Londres 59, Alger 37, Mexico 19, Lima 12, 15, Constantinople 41, Marseille 43. On the back of the case there is another list of cities (take a look to the pictures). The wooden box is still in good condition. It is complete, opens and closes as it should. Has some damage on the back as can be seen in the pictures but nothing serious. The compass alone weighs a little more than 550g and the wooden box about 150g (around 700g compass + box). The silvered dial of the compass measures around 90mm in diameter. This is a nice a rare example that would make a nice add to any serious collection.
