Hello,
First post! Looks like it´s 1770 made.
I need some help reading this manufacturer hallmark.
Many thanks!

Hi and welcome to the forum.

This is the one of the marks of Thomas & William Chawner with a London hallmark including the date letter "P" for the assay year 1770/71.

Hello,
Thank you for your help.
I guess that mark is not on the list??
Regards.

It's on my list but hasn't reached 925-1000's list of London makers.
