I was researching an historical figure on the Isle of Man, Capt George Quayle (b.1751 - d.1835), and in amongst the museum's papers was this numbers grid which was part of his effects. The museum said they'd not been able to work it out. Amongst other things George Quayle was a politician, army captain, smuggler, traveller and supposedly a spy for British intelligence. He had hidden areas and rooms in his home and office building and built an elaborate safe that could only be opened by placing cannon balls of different weights in a basket in the correct order. He's very much an enigma and I'd appreciate help with this grid. Thanks in advance.
