Boubon Experts - Elmer T Lee Question

Are there any identifiers (on the bottle) to tell bottles apart noted from release to release?

Thanks.

There should be a date code etched or printed on the glass somewhere on the bottle. Been awhile since I’ve looked at one but probably something like B1526512:00. So bottled 265th day of 2015 at 12:00pm.

And if I’m not mistaken, the letter indicates the bottling line.

Found it on the side of my bottle.

Ok, so I know I’m late to this thread, but the bottle I have shows the following date code: W0390812:25

Can anyone help me to decipher this?
