A wide variety of cranks, see if I can put a name on some of them. From the left, I believe that is from an early gasoline or oil pump, because of the eyelet on the handle, this let it be padlocked against theft. Next looks like the handle for a common meat grinder. The big ones that clamped on the edge of the table. Third is definitely for a small gas engine, notice the ramp on the drive end that kicks the crank out when the engine fires. Something like a LeRoi? or Cushman, Delco Light Plant had one similar to that. The big one looks like the crank handle on my stand up wooden corn sheller. Five is tough, could be from any kind of early machine tool? Because of the steel handle. And no.6, not sure of that one at all.
