A formal report from the Customhouse (signed by H. Pelham, J. Mead, W. Musgrave, and Edwd Hooper) to the Treasury Lords responding to proposals for improving Isle of Man revenue. The officers recommend full annexation to Great Britain (specifically to Cumberland) rather than implementing separate trade regulations, arguing this would prevent smuggling and integrate the island's customs administration with English ports. This represents the official revenue perspective on constitutional settlement two years after the 1765 Revestment.
