S & B Solomons 'Hutchinson's Improved Patent' Compass c.1874 Tommy Gun with a beam of 28A Hutchinson's Improved compass, signed by S & B Solomons, dating from c. 1874. With a bronzed brass case, prism and vane sights, very finely engraved aluminium ring dial, transit lock, and tripod mount on the base, this type of military compass was a development of the 1812 Schmalcalder Patent design. Unlike the Schmalcalder instrument, the Hutchinson's has a solid top plate, with a small viewing window near the prism, and an aluminium ring dial.
