A rosewood and brass Barrel Travel Inkwell.
The inkwell is banded in brass fixed with pins as a coopered barrel would be held together by metal rings. The top third of the barrel is the lid and is removable with a half turn to release it. The interior of the lid is fitted with a half ball that is likely to be made of gutta percha. This acts as a seal to the mouth of the glass ink bottle. The bottle sits on a spring which forces it up to make a tight fit to the ball. The bottle is held in place by a decorative brass ring.
The barrel is turned out of one piece of rosewood and the inkwell has a good weight to it. This is a good looking, tactile desk piece. Mid 19th Century.
