Or how about those Sonic Tronic pneumatic actuators that you could pair with any mechanical retract. They were actually strong enough to handle those Goldberg retracts.

They weren't "SonicTronic" actuators, but "Sonic Systems" actuators. Different company. I used them with mechanical retracts in a Mach I in 1974-5.
I have a manual if anyone needs one! Used them on my fourth retract gear setup with CAS retracts. They worked pretty well.
