On 20th March 1801 William Welch of Exeter sent in 8 pairs of tongs for assay. The important note is that the Assay office register specifically states that it was William Welch - Exeter. This is clearly a different William Welch to the one at Plymouth Dock. William Welch of Exeter went on to submit a lot of work for assay. He died in 1827.
