Was this commonly used by mountain men? I know the masses living in the rest of the country used it extensively on firearms and fine machinery, but I'm just wondering if it made it out to the "fur fields". Also an interesting related fact is that jojoba oil is a virtual dead ringer for sperm whale oil. So if the Rocky Mountain trappers used whale oil, I'd feel as PC as possible bringing a little glass bottle of jojoba oil to the rendezvous. :imo:
