Mysterious 12AU7/ECC82 Vacuum Tubes

Not the best but better than your average lot of standard AU7's, green letter Sylvies, RCA's etc. I find them to be on par with my Holland based Amperex "flasher", maybe bit more crisp with the treble while my flasher's are more warmer and mellow.

New case! :D
 
I have just won two auctions for some unusual French Radiotechnique tubes. They are labeled "12AU7S", which I think means they're selected as premium tubes. The printing is kind of gold-colored. The getter is angled and looks like no other I've seen before. Has anyone ever seen/owned such a tube? I couldn't find any other myself.
