Archer, you are welcome. To retract the gear, you just need to start cranking. There is an over-center down lock, plus the gear and chains. You get some feedback as the gear passes about halfway up as it gets into the prop's blast, which tends to make the cranking a bit harder. It is also best to keep the airspeed below 100 knots while raising the gear to avoid more air load.
The crank is connected to two toothed gears on the engine side of the firewall bulkhead and the crank is connected by what look like motorcycle drive chains. There is a ratchet which prevents the handle from unwinding while you are raising the gear. To lower the gear, you flip a small lever next to the crank to disengage the up-ratchet lock. The handle is then cranked up just a bit to release the ratchet. At this point the gear could free fall down if you don't hold onto the crank and control the lowering. I know at least one incident on another FM-2 when the pilot let the gear free fall a few times and it ended up damaging the teeth of the gears and stretching the chain. As I remember, one gear failed to lock and may have partially collapsed. I was not a witness, so this is based on what I was told.
It has been a number of years since I flew an FM-2 but as I remember there was no real indicator of the gear position, other than the position of the crank handle. That was why I counted the turns, especially when lowering the gear. If it stopped before 29 turns down, it could be a problem. Fortunately, I never encountered that.
It would not surprise me if Gerald may have rolled it to crank the gear "down" but this would typically only be "legal" at an air show

. Many times I flew the Wildcat as the "good guy" in the Tora act, launching directly underneath the Zeros and Vals and having at least one Kate coming the opposite direction of my take off. He would be at maybe 75 feet high on the left side of my runway so I had to pull the power back and not climb much higher than that while I cranked up the gear. Once out from under the Tora "furball" I quickly climbed up to engage a Zero and shoot him down a few times. At smaller shows with fewer Tora birds, I would often join the "Zero circle" which was interesting.
I hope this helps you understand the practical operation of the gear. If not, ask away. Fly safe.
