I'm getting green with envy too.
As mutti said, most jars of the modern style have interchangeable lids/bands. I know that I have ball, mason, kerr, atlas, and some really small brands - such as Brook - and all the lids are interchangeable, from half-gallon to half-pint, even on the colored jars. Most of these jars date from the 30's - present, and we've been canning in most of them since at least the sixties. The really older jars are a bit different size - such as the zinc lids, or some set up for wire bail or screw-on lids, but we don't use those for canning.
Thanks for the links mutti - I'll have to look at those on my next downtime and maybe see what I actually have on the shelves.
