Case for Morland's calculating machine

Leather case for Morland's calculating machine, probably made in London, 1666-1695

Pocket instruments were often supplied with carry cases such as this leather case for Morlan's calculating machine. Originally it would have contained a stylus for operating the machine and possibly a small pamhlet explaining its use, neither of which have survived.
