Letter from Dan Mylrea (Collector of Customs, Isle of Man) to Charles Lutwidge, confirming that the Governor has approved production of ten years of import/export books (Ingates & Outgates) upon receipt of proper authority. Mylrea also confirms sending a copy of the Book of Rates and offers further assistance with revenue collection. This document is crucial evidence of Lutwidge's investigation into smuggling losses and the Treasury's interest in Manx trade records immediately before the Revestment Act.
