Olive oil

I read that olive oil has been used in cooking, as medicine,
to soothe ear aches, in lamps, and in guns.
Before petroleum oil was available circa 1859 people used
olive oil to lubricate and clean guns. It left the bore of
muzzleloaders smooth as glass and easy to load and clean.
Some gun oils have a strong odour which many recognize.
It might be just was well if your piece smells like olive oil.
I have not yet used olive oil in my guns, but I will use it on
one to see how it does. If you have used it on guns
please tell us the result good or bad.
