I dont know how to convert to F but here is what I found by placing
a winder, and the oil and grease in the freezer ( -30 degrees C)

Using the winder straight out of the freezer is miles ahead better
than it was before a cleaned and lubbed it :-)
[observations about the grease snipped out]
-30C is -86F. This more than answered my question. Neither man nor beast
should be out in that cold. If it survived that, it should work on a
Himalyan trek in winter. Maybe not the batteries, but at least the winder
would if power is wired to it.
You really have a freezer that cold?
I'm surprised your hand didn't stick to the winder :-)
Thanks,
