It looks like a Lindemanns Frambois bottle. If it is, it can be capped and it will hold pressure well, but you need European caps (29mm, I believe). You also have to adjust your capper. If you have a red baron capper, you have to pull out the crimpers with a pair of pliers and turn it around. The bell is a little small, but it does work.
If you just have the one bottle, I'm not sure if it would be worth all the trouble.
