Need help with black Hurst shifter knobs

I'm going to order one of these. Do any of you know for sure if any of these come WITHOUT the Hurst logo on it? They all have this description in common. As a matter of fact, all of the specs are the same with the exception of the notes I've posted below.

The third one does appear to have the logo on it, but what about the others. These are listings from Summit Racing.

From Jegs:
Under the heading "Classic Knob with Logo"
Classic Black Ball, 3/8'' - 16 Thread

Mine came with nothing more than the 6-speed pattern - no Hurst logo. I got it from MarylandSpeed.

HUU-1630156 has the Hurst logo, you can just barely see it in the picture on each side of the knob.

Keep in mind 3/8 by 16 is the thread size of the GTO shifter Lever

Actually, the 7201 Hurst lever (supplied with Hurst GTO shifter) is 12mm x 1.75 I believe.

I could be wrong...

Looks like I'm stuck with the Hurst logo.
