I searched on this, but the only information I found isn't exactly relevant to this. Usually I've found the date on bottles are fairly easy to find, but on this 375ml of OWA107, it says "84" on the bottom of the bottle. This shocked me, and then I noticed the bottle is not OWA107, but "Old Weller The Original 107 Proof"
I know there was some questionable "Antique" labeling between SW and BT. it's a 88004 02569 number, which I believe is all BT.
After letting it breath, it has a bit different flavor then the 90 proof. It's got a deeper flavor (not strictly proof) as well as a more grainy flavor with less alcohol in the nose. This doesn't taste like the new OWA107 I have, and enough of a different profile from the newer BT wheaters that makes me wonder.
Edit: Adding in tasting notes.
Nose: more earthy then Lot B, vanilla, BBQ?, butter, sweet,
Initial reaction: tingle showing the proof, sweet, almost a hint of rye spice for a second? I don't understand where this flavor is coming from.
Middle: full and deep for a wheater, vanilla, heavy carmel, cinnamon or pepper, corn syrup, grains. More body then expected.
Finish: Long, tingle without burn, sweet, fading to light carmel flavored wood
If I was crazy, I would say this is a OW(A)107 label on a bottle of something else. It tastes like it's 90 proof little brother, with a splash of WT101, and added depth. I wish I had more then 150ML or so left of it. Am I crazy?
