That's interesting Stan. When I was plumbing the gas lines in my house, I was having trouble getting clean threads on the 3/4" and 1" black pipe. I tried using some old 1950's-60's vintage Ridgid Sulfur Lard cutting oil that came out of my grandfather's garage, and the same threading dies cut perfect smooth-as-glass threads on the same pipe.

Lard was used as a muzzleloader patch lubricant until petroleum lubes became cheap after Drake struck oil in 1856. And that is when shooters began having a lot more problems with corrosion causing rusting and pitting of bores. I now use the Thompson Center Natural Lube, and no longer have any problems with after rust.
