I will endeavour to get a photo on the forum but for now can anyone help? I am completely new at this.
The first mark is a crown - then the mystery mark is a fleur de lis - at least it looks like one, it is three feathers joined at the base. Then P G S. I do understand that the font needs to be seen to identify the P G and S. they are all the same upper case font.
Am I correct that the crown is Sheffield?
Thanks Red
