Does anyone know about this flatware?

I am new to silver and could use help finding information on Gold-Tone Flatware I have.

The long knives are stamped T.W. & Sons Refined Steel on the blade.

There are 4 square stamp markings on other flatware.

Any information on these pieces would be helpful.

Thanks in Advance!

This appears to be an electroplater’s mark, but I can’t be sure exactly whose, possibly T Wilkinson & Sons of Birmingham, although it doesn’t match any of their marks which I have seen.
