Two decorative glass bottles heavy silver coloured stoppers (South Croydon CR2)

I've lovedand displayed these bottles for several years. A few years ago they got knocked off the mantelpiece and the metal collars that hold the stoppers detached from the glass bottles. I've continued to display them but now decluttering and don't have the heart to throw them away. I'm sure they could be fixed somehow. Collection from South Croydon CR2 6PT
