the pictures have a ring around the middle silver part. I don't think those are the q-35's maybe another quadraflex? Look very close . At least I think they are differnt maybe others can see that too. The last frame there doesn't even seem close in my opinion.

Yea you're right. The ones in the screenshot has a ring around the protruding part, and the protruding part doesn't stick out as much.
The right side cups don't have that knob. 
 
But they look pretty much the same. Probably Quadraflex or some other replica version of it.
