How many volumes of c02 will this Anchor bottle hold?

[BrewingTravisty]

I have a 1.5 liter bottle left from the Anchor 'Our Special Ale' that I bought for Christmas, and it seems like a very sturdy bottle and the beer was highly carbonated. I'm wondering if anyone knows if it would hold champagne levels of carbonation?
