4seventy assuming everything you posted is true, and I have no way of knowing it isn't, I have just one question, I would like you to answer! Why are all my Whtiworth rifles stamped " Whitworth, Manchester, England", and the marks on the barrel and action are indeed a crown over "V" ? The reason I ask this question is, the USA has a rule in the import law that requires products imported into the USA, have the country of origin perminantly affixed to the product. In the case of the Whitworth, the CZ is affixed to the action, along with the Whitworth, Manchester address, and the importer Interarms. The other rifles imported by interarms only have the CZ, and the importers marks on them. To me, this follows the import laws for the USA, but I can't say for other countries.

The whitworth issue is one that sorely needs verification, and it is welcome, no matter how it turns out, as long as there is some backing for the data!
