Brass Telescope Keyring
Spy out a new adventure with our brass telescope keyring, which can be used as a miniature telescope. Telescopes were useful at sea to spot potential dangers (be it enemy ships or rocks) from a distance where the ship could react to escape or engage. Nelson famously held up a telescope to his blind eye at the Battle of Copenhagen to ignore orders from his commander to withdraw before completing victory.
