Was digging at the 1890's spot today, only second time I've gone there, and found this among a few other odds and ends. It's a lid to a tub of toothpaste made in Manchester England, likely late Victorian age to the early Edwardian-era. It includes the words "By Appointment" and I'm pretty sure that has something to do with the royal family's use or approval of the product in some way. I have seen similar such lids online in which some have this written on them while others not - so perhaps the appointment was for some years and not others.
Another interesting thing I found was a still-corked bottle embossed "BEREZA PRODUCT -Natural Flower - Perfumery Co. - St. Petersburg And New York".
This bottle is quite pretty and still contains what appears to be about half the original product within. I didn't remove the cork but stabilized it with vaseline so it won't dry out (maybe the product can stay fresh for another few centuries). It is a hand-finished tooled-top bottle. I don't know if the St. Petersburg that is referred to on the bottle is Tsarist St. Petersburg in Russia pre-1914 or if it is referring to the US-based city St. Petersburg Florida, which was founded in 1888. I'm going to assume it was the Tsarist Russia St. Petersburg as this would make more sense. This city as we all know would be renamed Petrograd in 1914 and then Leningrad in 1924 (in 1991 it would be called St. Petersburg again so it all worked out in the end).
