I restored an Martini Henry once and it was covered in what I concluded was rancid yak butter. Seriously, many of my 100 year old machining books have all sorts of animal based recipes for cutting and lubricating compounds. Maybe they are still being used. Or perhaps it is something out of the Soylent Green factories
