Linlai E 6sn7 tubes

My E-6SN7's have a serial number inside the bottle. All authentic Linlai's do. I wonder if Viva's tubes have it.

This is the email I received from Viva tubes this morning;

Hi Dan, they are indeed legitimate. We import them directly from China. Thank you for your order. We hope you like them.

I called earlier, with no response. I’d like to know if these tubes are legitimate, or are they copies? Dan M.

I just sent them an e-mail too. They are not taking calls: 

"Good morning,

I have a question after reading that Grant Fidelity was also selling the new Linlai E 6SN7 Global tubes. They look different and have different branding than the ones you are selling. Are the Linlai E 6SN7 that you sell the same tubes but have different batch manufacturing which makes them look different?  I want to ensure that I am receiving the new Linlai Global tubes as depicted in the manufacturer's site: Linlai™ Global Elite E-6SN7 Vacuum Tubes (pair) – LINLAI™ Global Vacuum Tubes (linlaiglobal.com)

If these are not the same tubes, then I would like to return them as I thought I was ordering the Global Linlai edition, and not the Globe version which you are selling. It seemed to me a little confusing because you sell these with the word Globe in the selling title, which I assumed also meant the new Global versions. If these are not the same, I would like to start the return process based on me ordering the wrong tubes. Thank you. 

I use these tubes for the output stage of my CD player. They replaced a set of insanely-expensive Brimar CV-181 tubes that were damaged in a tragic feline accident. Probably 1/3 the price and equally-wonderful sound quality.

Not wanting to deal with eBay and China, I bought my first pair of Linlai Elites from Grant Fidelity. Then came the tube crisis and huge price increases so I took a chance buying a pair Psvane UK's from China off eBay since they were just for the buffer stage of my Freya + which is my first tube preamp since an AR SP3 in the 70's. They are fine. One of Elites from GF went bad, so while waiting for a replacement from GF, I bought a pair of Elites from China. They came and are fine also, so two good experiences with eBay and China, who knew! Now with my replacement Elite back from GF, I've replaced the Psvane UK's and now have Elites in all positions. I didn't think it would make a huge difference having the Elites in the buffer but it did, hugely better especially in the low end both in quantity and quality and definitely worth the additional $$ and this is with only about 15 hours on the new Elites.

Also I think there is confusion about the Globes, not Global's,  sold by GF. They are not Linlai, I believe they are Shuguang iirc.

eBay dealer names upon request as I may have just gotten lucky so I can't really vouch for them.
