FWIW, here is what he says under Q&A on his site:

"Q:

ARE ALL OF YOUR TUBES NEW?

A:

Most of them are. On my audiophile tube list, it states directly if a tube is NOS or used. Most of my regular stock list are "NOS" or New Old Stock, meaning the tubes themselves are old, discontinued, and/or obsolete. Ninety five percent of my tubes are over 30 years old, so they may not always look "new", and may not be in a new looking box. Many boxes have not survived the years, and I will supply the tubes in clean white boxes. Some of my tubes were obtained in jobbers boxes, which are egg carton type boxes or styrofoam crates. While these are NOS tubes, they never had a box of their own. I have also bought tube caddies full of tubes. It was a common practice to recycle the boxes in tube caddies, and refill them with tubes from bulk jobbers boxes. While these tubes are also NOS, the tube box may be worn and have the tube number hand written on it, with the original type number crossed off. I will try to send you a tube with a good label in a good box, but with high demand tubes, this may not always be possible. This is because all of my tubes are vintage. I do not sell recently made Chinese or Russian tubes, which may look newer and have a new box, but typically do not perform as well as vintage tubes. The big exception here is antique or "two digit" tubes. These are all over 60 years old, and it is nearly impossible to tell if a tube has ever been powered up in a circuit before. These tubes, like all of my others, are tested as NOS. I test every tube I sell, and these must test as new or I will not sell it as such. All of my tubes, even those I sell as used, carry my 30 day satisfaction guarantee."

Under NOS Mullard 12au7s, much of what he lists specifically says "White Box".
