Very nice Scandinavian bismar made of wood. The beam is 29" long and have a graduation with little iron nails. The load hook is hand forged. The wooden weight have four calibrations ( lead ) and show as  verification mark the
Crown. Also you see two crowns and the date 1792 on the weight + AB 2 7 and a 5. Sorry I do not know what that means.... maybe next time more about this !
