Unfortunately those "cobalt blue" type bottles seem to be fairly common. It does bear a resemblence to products from AD, who have used that style bottle and foil label for quite some time. I do recall that almost every one of their products I had had a top that would leave behind a "security ring thing" around the neck that broke off the cap when you first opened the bottle, and I don't see one on this bottle. Also I've never had one of their labels wear that completely. I'd be tempted to say it *isn't* one of theirs.
Some other clues is that it *isn't* a dropper top (rubber bulb) or spray top. Does it have a "reducer" insert in the neck of the bottle?
Do you recall where/how you bought it? Store, internet purchase?
Not much help I know but sometimes it's a process of elimination. (Right Mr. Sherlock Holmes?)
