The excitement started soon after 9am on Wednesday when Mr Murray, 68, who was also responsible for finding a hoard of Roman coins a couple of years ago, was working in a pit previously excavated in Victorian times.
He said: “There was a lot of rock around and I noticed a piece with a line on it. I thought it might be a piece of something.”
He called Mr Wilmott and the two men carefully uncovered it.
