"GLASTON / BURY" handstamp, 1794

The "GLASTON / BURY" handstamp below, on an entire dated February 1794, was previously only known used 1796-1798. This entire brings the date forward two years.  The handstamp previously in use at Glastonbury is only known used until 1785 so there is still an eight year gap when no handstamp is known.
