flip top bottle conversions

[Boar Beer]

Does any one know where to get these flip tops to add to my champagine bottles. These guys work great and I have a huge collection of nice old bottles that i would like to store my beer in. I was told they may have come from France

Would wire hoods be a good option in this case?

I've never seen them...I would love some.
