    BigTreeKeys and the team: Again, many thanks for the research! I never would have been able to access this information without this website! Don't understand the difference in the date on the key and the information you provided, however. Sally

    The date of 1880 I gave was just the date that I think the image I provided dated to. It doesn't mean they didn't make that lock since 1873, just that it was being sold in 1880.

    A patent date merely means an object was made on or after that date. Manufacturers sometimes left the patent date on goods long after the patent was granted, as a point of pride as well as a warning to competitors. And in many cases a product was manufactured well before the patent application was granted, usually stamped "Patent Pending."
