I have used neatsfoot oil on bone, antler and leather for as long as I can remember. I mainly have used two brands, Brownell's and Fiebings. I have used both regular and compound and can detect no difference in what they do to, or for, the item being treated. A quality object made from bone or antler will benefit from being treated with a soaking in neatsfoot oil occasionally. The 'soaking' can be a week to a month. "occasionally" can be one a year or once a decade. Just watch your item and be alert for shrinkage. FWIW, I see no difference if using baby/mineral oil.
