Hi there, John,
That looks like a good haul!
Your photo of the cold chisel stirred my memory so I've just dug out a copy of the Moore & Wright catalogue 'of Precision and Hand Tools', 4th edition, January1963. On page 124 it shows their range of 'Sure-Cut Chisels' and says this about them:
'These chisels are made from a new non-tempering Special Nickel Alloy Steel. They can be re-sharpened with a file but are so tough that they will do the hardest work. The flat section gives a firm grip, and they will not splinter under severe service.' [Their emphasis, not mine.]
They were available in eight different sizes from 5/16" wide by 4" long (price 1s 9d each) to 1⅛" wide by 10" long (price 8s 0d each). They also give the following:
'TO HARDEN - Heat to 830° C (bright cherry red) and quench in oil. FORGE at the same heat. It is very important that the above temperature be adhered to. It neither forges nor hardens well at lower or higher temperatures.'
I still have one of the smaller ones, one of the first tools I ever bought and while I was living in the family home. My father, an accomplished woodworker, would not accept that a chisel capable of cutting metal could be sharpened with a file.
