I bought an FHA-17C actuator from eBay. It was cheaper than normal,
for parts or not working.
It clearly had the cables cut off, so I decided to gamble.
It turns out that things were worse than I hoped.

I am seriously considering trying to make a new flexspline. I mean,
how hard can it be?
Based on what I know about harmonic drives, extremely hard.
Each mechanism has a serial number on both tooth gears to be perfectly
matched. You cannot mix and match. That explains high cost.
I happen to get my hand on few gears like that. See

I know that people play with 3D printed plastic ones for toys etc. but
that cannot replace metal.
