It would be interesting to see the Sir Joseph Whitworth Fluid compressed Steel tubes sourcing numbers from the pre-1897 merger with Armstrong & post merger. So if all Sir Joseph Whitworth Fluid Compressed Steel tubesets are chopper-lump and considering the hook to be an original integral component, then original raw cast would have the hook and the cast mold would have the female counterpart of the hook? Now you collectors of those sporting weapons from the little British Isles don't throw any stones just yet, but I've read opinions that Purdey consider Krupp steel tubes from 1897 to circa 1900. We know that Kilby used Krupp 3 Ringe Steel, so are there any know Purdey offerings with original Krupp steel tubes?
Kind Regards,
