I was fortunate enough to have been gifted 3 1/2 quarts of "old" Spencer Kellog leaded boiled oil that had alconate (sp?)root soaked in it. Produces a great finish. You can buy cold pressed oil from Natural Pigments, as well as powdered white lead and make your own, or keep an eye on E-bay for an old can. I have bought several. To each his own. Part of the fun is trying different things and keeping what works. For me a BLO finish works well and looks great.
