Hi there iv come across this bottle stopper and just wondering where it comes from what's it from? Has the number (Rd no 295260)most grateful for ent help.thanks jim
It is a British Design Registration Number, similar to a patent number.
Rd. No.295650 shows the design was first registered in 1897, however, the item can be manufactured long after that date.
Could have been a broad range of products. I've seen similar stoppers on Morton's table salt and Swan brand table salt bottles. A very similar style stopper was used in the US for Mellin's Infant Food bottles.
