[CR]aluminum water bottle source?

Along with the integrated headset Bianchi frame/fork I bought Sunday, I also picked up a REG handlebar mount single bottle cage with the spring clamp. A little cleaning got rid of most of the rust - but now I'd like to have a classic style aluminum bottle with cork, similar to the one on Coppi's Masianchi in the photo Rob pointed to at: http://albums.photopoint.com/j/AlbumIndex?u=1603921&shownewphotos=true

I've seen ads for current Sigg water bottles that might look similar; are they? Or is there a better match that can be bought for less than it's weight in gold?

Thanks,
