2th July 1789 - Patent No 1690 for "chape & fastening for buckles " granted to a Thomas Freeth.
This almost certainly relates to the man who entered marks as a bucklemaker in 1787 and 1797.
I've only ever seen two pairs of shoebuckles with Freeths Patent stamped on them. Both pairs made by Charles Hougham ! Never seen one on a Freeth buckle !
As would be expected the patent is a modified version of Eley's Patent.
