What brands are the stock tubes that came w/ S.F.?

I have some E188C that I just digged out of my junk earlier and I am wondering what brand they are. I mean the true brand. Need to know how what they are and how much they are worth because I am planning to get rid of them...

They are labeled:

1.) GOLD AERO for SONIC FRONTIERS EC188C with Gold Pins
Wondering what the true brand is, they have seamed tops.

2.) GOLD AERO EL34 special selected for SONIC FRONTIERS.

I am def. not a tube-person...
I dont know if any of you are familiar with these tubes.
I dont think that SF has changed their tube sources that much so they should be as-usual as what you all who owned a SF has got as the stock tubes...

Any feedback will be greatly appraciated!
