Letter from Dan Mylrea and John Quayle (revenue officials) to the Duke of Atholl enclosing a demand for customs duties from merchant John Taubman, with Taubman's detailed response. Taubman contests the duty charges, claiming he was misled about the Revestment and argues he is owed £300 plus interest lent on harbour security now transferred to the Crown. The letter documents post-Revestment revenue collection conflicts and merchant grievances.
