Wells to Tunbridge Wells in 1758

The entire below was sent from Wells, Somerset to Tunbridge Wells, Kent in 1758.  As it was addressed to "The Right Reverend The Lord Bishop of Bath & Wells" it went free in the General Post, and has been marked "P" for Privilege to indicate that no postage charge was due.

The "WELLS" handstamp is crisp and clean and matches SO 893 (30x6 mm, previously known 1759-1766), an example of which from 1765 is shown below.

This extends the usage earlier by one year.  SO 889 (31x7 mm) is known used 1754-1758, but unfortunately I don't have an example to compare with.
