An addendum to my previous post. I went into my stash of Svetlana EL34 and I found some which were made about 10 years after the ones I mentioned previously. They had the "Winged C" logo and in descending order the following:
EL34
Made In
Russia
0502
Totally different from those in the picture in the ad. Draw your own conclusions, but mine have not changed.

FWIW.
I don't know what those are but they are not NOS Winged C's. 
Look here (you can click on the photo to enlarge it) and check out the printing on the tube. Much different.

It the price is too good to be true.....
I have numerous Svetlana and SED EL34's, all purchased in mid 90's, all look like the tubedepot tube.
