They gave the steel body a very convincing wood-grain finish.  Original tuners, tailpiece is vintage but may not be original to this guitar and the same may be true of the cone.  You can see the outline of the National \"badge\" logo on the face of the headstock, serial number B2916 is stamped into the upper edge of the headstock.  The original finish on the body is in great condition, but there is wear to the cover over the bridge.","brand":"National","offers":[{"title":"Default Title","offer_id":46271498289351,"sku":"NARDUOSQU-B2916","price":2850.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0503\/4947\/3991\/files\/1421001_d4df2837-c225-42f3-a3c1-0dc2487ce52c.jpg?v=1780487268","url":"https:\/\/www.gryphonstrings.com\/products\/1937-national-duolian-squareneck-resonator-guitar-used-24958","provider":"Gryphon Strings","version":"1.0","type":"link"}
