Hi _all
By 1953 there doesn't seem to be any sign of Hodkinson etc unless they're too far out.
There is an advert though for English Steel with quite a bit of information. (Kelly's Manchester, Salford and Eccles).
English Steel Corporation Ltd, Tool Steel, small tools,
Castings and Drop Forging Manufacturers &c.
North Street Works, Openshaw, Manchester
Tn East 1371 (PBX), TA "STEEL CORPO";
registered office, River Don Works, Sheffield 9.
Also, on next line:
English Steel Corporation Ltd. Steel mnfrs.
7 Chatham St 1, Central 6775
I don't know what it all means, but I hope it helps. Let me know if I can help any more.
Best wishes
Emms
