I am relatively new to the board, but I've found it very interesting.
On the thread conceding I. (John) Wilson, one contributed attached a jpeg:
(1892) - (1919)
Cutlery in general
Ref. 1892, 1919, 1974
And then below the wording, there were what appeared to be four different trademarks for John Wilson.
Does anyone know when each of these trademarks were used by the John Wilson company in Sheffield.
Thank you in advance for all your help.
