I own a STUN Runner. It's not that one.
Agreed -- unless it was modded with an extra Y-axis spring, thumb buttons/handle shells, the Y-axis sriker plate was removed, and a custom-built metal mount was added.

Pretty sure it's not from a Hydra since the parts breakdown shows no gears on the back and the angle of the mount looks different. (pgs 35 and 12 of
owner's manual)
It's also probably not from Lock-On, based on the third picture in
this thread. (no gears on the back)
I looked at the yoke cover (which has a reprinted star wars overlay like the one in the video) and noticed to gray stripes peeking out from the original sticker underneath, leading me to believe it is a Lock-On yoke.
It's hard to say for sure without the part number of the rear frame (Star Wars = A040236-01, Stun Runner = 040236-02, etc.) or some other distinctive identifier.
