Long Arm Drill?

[TopCrusader]

Hello all,
I am not extremely familiar with long arm drills so I could use some help identifying this. My first guess was from Choy Li Fut, Hung Ga, or Tibetan White Crane?



The drill starts with a outward swinging punch (backfist?)
The last two pictures show a uppercut followed by a groin strike to finish the drill.

Look familiar to anyone?
Thanks
