{"product_id":"crescent-dial-underside-of-base-f2059-1","title":"Crescent dial, underside of base","description":"Crescent dial for latitudes 0-90 north. The dial-plate is gilt-brass while the leg and levelling screws are silver. The hour-plate is also gilt-brass, with a silver date scale and hour scales, but the gnomon is possibly steel. The latitude arc and plumb-bob support are silver, but the bob is gilt-brass. The dial displays a perpetual calendar and a table of latitudes, titled 'Elevation Poly' which provides a fairly large list of places in Europe. It is engraved 'Masig a Londen 52' on the obverse side of the dial-plate. Masig was the London agent of a number of dial makers. The maker of this dial was probably either Johann Martin or Johann Willebrand.\u003cbr\u003eprobably Johann Martin or Johann Matthias Willebrand","brand":"prodigi","offers":[{"title":"Fine art poster \/ XS: 30 x 30cm \/ none","offer_id":57026128576894,"sku":"GLOBAL-FAP-12X12","price":22.95,"currency_code":"GBP","in_stock":true},{"title":"Fine art poster \/ S: 40 x 40cm \/ none","offer_id":57026128609662,"sku":"GLOBAL-FAP-16X16","price":28.95,"currency_code":"GBP","in_stock":true},{"title":"Fine art poster \/ M: 50 x 50cm \/ none","offer_id":57026128642430,"sku":"GLOBAL-FAP-20X20","price":38.95,"currency_code":"GBP","in_stock":true},{"title":"Fine art poster \/ L: 70 x 70cm \/ none","offer_id":57026128675198,"sku":"GLOBAL-FAP-28X28","price":54.95,"currency_code":"GBP","in_stock":true},{"title":"Fine art poster \/ XL: 80 x 80cm \/ none","offer_id":57026128707966,"sku":"GLOBAL-FAP-32X32","price":69.95,"currency_code":"GBP","in_stock":true},{"title":"Fine art poster \/ XXL: 100 x 100cm \/ none","offer_id":57026128740734,"sku":"GLOBAL-FAP-40X40","price":82.95,"currency_code":"GBP","in_stock":true},{"title":"Framed picture \/ XS: 30 x 30cm \/ none","offer_id":57026128773502,"sku":"MUS-CFPM-12X12","price":59.95,"currency_code":"GBP","in_stock":true},{"title":"Framed picture \/ S: 40 x 40cm \/ none","offer_id":57026128806270,"sku":"MUS-CFPM-16X16","price":79.95,"currency_code":"GBP","in_stock":true},{"title":"Framed picture \/ M: 50 x 50cm \/ none","offer_id":57026128839038,"sku":"MUS-CFPM-20X20","price":119.95,"currency_code":"GBP","in_stock":true},{"title":"Framed picture \/ L: 70 x 70cm \/ none","offer_id":57026128871806,"sku":"MUS-CFPM-28X28","price":159.95,"currency_code":"GBP","in_stock":true},{"title":"Framed picture \/ XL: 90 x 90cm \/ none","offer_id":57026128904574,"sku":"MUS-CFPM-36X36","price":204.95,"currency_code":"GBP","in_stock":true},{"title":"Postcard \/ Standard: 6 x 4in \/ Single","offer_id":57026128937342,"sku":"GLOBAL-POST-MOH-6X4","price":1.95,"currency_code":"GBP","in_stock":true},{"title":"Postcard \/ Standard: 6 x 4in \/ 10-pack","offer_id":57026128970110,"sku":"GLOBAL-POST-MOH-6X4-10","price":14.95,"currency_code":"GBP","in_stock":true},{"title":"Postcard \/ Standard: 6 x 4in \/ 20-pack","offer_id":57026129002878,"sku":"GLOBAL-POST-MOH-6X4-20","price":24.95,"currency_code":"GBP","in_stock":true},{"title":"Postcard \/ Large: 7 x 5in \/ Single","offer_id":57026129035646,"sku":"GLOBAL-POST-MOH-7X5","price":2.95,"currency_code":"GBP","in_stock":true},{"title":"Postcard \/ Large: 7 x 5in \/ 10-pack","offer_id":57026129068414,"sku":"GLOBAL-POST-MOH-7X5-10","price":19.95,"currency_code":"GBP","in_stock":true},{"title":"Postcard \/ Large: 7 x 5in \/ 20-pack","offer_id":57026129101182,"sku":"GLOBAL-POST-MOH-7X5-20","price":29.95,"currency_code":"GBP","in_stock":true},{"title":"Greetings card \/ Standard: 6 x 4in \/ Single","offer_id":57026129133950,"sku":"GLOBAL-GRE-MOH-6X4-BLA","price":2.5,"currency_code":"GBP","in_stock":true},{"title":"Greetings card \/ Standard: 6 x 4in \/ 10-pack","offer_id":57026129166718,"sku":"GLOBAL-GRE-MOH-6X4-BLA-10","price":15.95,"currency_code":"GBP","in_stock":true},{"title":"Greetings card \/ Standard: 6 x 4in \/ 20-pack","offer_id":57026129199486,"sku":"GLOBAL-GRE-MOH-6X4-BLA-20","price":26.95,"currency_code":"GBP","in_stock":true},{"title":"Greetings card \/ Large: 7 x 5in \/ Single","offer_id":57026129232254,"sku":"GLOBAL-GRE-MOH-7X5-BLA","price":3.5,"currency_code":"GBP","in_stock":true},{"title":"Greetings card \/ Large: 7 x 5in \/ 10-pack","offer_id":57026129265022,"sku":"GLOBAL-GRE-MOH-7X5-BLA-10","price":19.95,"currency_code":"GBP","in_stock":true},{"title":"Greetings card \/ Large: 7 x 5in \/ 20-pack","offer_id":57026129297790,"sku":"GLOBAL-GRE-MOH-7X5-BLA-20","price":33.95,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2785\/2654\/files\/f2059-1.jpg?v=1772709862","url":"https:\/\/prints.rmg.co.uk\/products\/crescent-dial-underside-of-base-f2059-1","provider":"Royal Museums Greenwich prints","version":"1.0","type":"link"}
