I had an George Ibberson & Co, Firth Stainless, from Eaton's Co had a nice violin on the tang, unfortunately, that blade had a crack in the toe and got chopped down...

Here's a better pic of one,...

Here's one of my W&B's, it's approximately 1810-1830, and you can see on the blade, "Improved Silver Steel".

Very nice, but the blade is most likely, "Silver Steel", and the England stamp on the tang means the blade was made post-1900.

Hope this helps.
