"In one instance only before the fourth decade of the 17th century did a Lord Mayor-elect (or about to be elected), who was not already enrolled in one of the great Companies, fail to translate himself ([immediately enrol in one of the great Livery Companies]). This was Thomas Andrewes, ..., who was appointed to succeed Abraham Reynardson, the Royalist Lord Mayor, on the latter's deposition in April, 1649, and having served till the following October, was, after a year's interval, again chosen for the year 1650–1651. I know of no explanation of the non-observance of the rule in his case, and can only suggest that it was one of the many irregularities of the troubled period of the Commonwealth." (Beavan p. 832)
