Hmm, I can't even see a seam from here. And it does have those concentric rings consistent with a turn-moulded bottle. To me it looks turned. This one's irking me a bit, I really want to determine whether this one's old or not, because for whatever reason it's not so obvious, it's a tricky one.
When you get a chance, if you could get a head-on picture of the top, base, heel, and any seam if there is a seam, that'd be awesome. Also, is it dust, condensation, or haze/sickness that is giving it that cloudy appearance?
