Ian â€” as I said before, your whatzit's patent lettering could well be a UK patent, or a patent from other bits of the old British Empire; suggest Australia, New Zealand, India, Canada, and South Africa if you get no joy from London, although 1866 seems to me to be rather early for all of them. I think you might find that all of these old bits of Empire relied upon the London Patent Office then.
And, while on the subject, what happened to the two Hayward design registrations I told you about early last year? â€” I can't find any mention on your Hayward pages. Did the email go walkabout? Do you want it again? I know you received the Edmonton insulators registrations okay including the third, unknown registration.
HTML is not available on this board, despite it saying that it is. However, the &... and &#... character actors work fine, but only once. If you edit your reply you have to put them back in again. This is useful for square brackets in samples of BBCode, showing others how to use it.
