One of our astute members(actually posted on this thread) has reminded me that S,D&G(Schoverling, Daly & Gales) was the Krupp authorized importer/distributor for the U.S. of A. and so I don't think it would be a stretch at all to say they were the source of Whitworth compressed fluid steel tubes for the U.S. of A. Curious as to how they sourced & their ledger would be a goldmine of info.

Kind Regards,
