Lionel Crabb was born in London to very humble beginnings. It wasn't until joining the Navy in WW2 that he discovered a love for diving - he was given the nickname Buster, after Olympic swimmer and action hero Buster Crabbe.

Lionel 'Buster' Crabb was sent on many dangerous missions around the world, including removing limpet mines from ships.

Sadly, the work he loved, made him a prime target for attack...

The last known whereabouts of Buster Crabb was checking in to the Sally Port Inn in Old Portsmouth, along with a colleague, Mr Smith. It is believed the two were employed on an espionage mission to study a Russian ship docked in Portsmouth  - tensions between Britain and Russia were high during this time as the Cold War continued.

The Russian military believe they saw a diver snooping around their ship and Buster was never seen again...
