There is nothing "hybrid" about it. It is a 7-element. It is simply an early production 7-element. If the IR mark is to the left of the f4 mark, it is 7-element.

You can see in the pictures of the "protruding" rear element that it is not "protruding"

7-element on left, 8-element on right.

My copy of the 8-element has the highest serial number I've seen on an 8-element.
