[TowerTalk] Need help identifying some antenna pieces

[Jim Pruitt]

Please excuse the question if this is no the place to ask.  I recently
acquired some various antenna pieces.  2 items like like elements from a
beam but both look like they have a small rotor in them at the center.
Both are New-Tronics (Hustler?) but when I google for images I get little
and results return mostly Hustler mobile antennas and Hustler verticals.
This is not a vertical.  I wondered if it was not a rotatable dipole but it
made more sense that it was part of a yagi since both pieces were not
identical but similar.

Thank you for your help.
