I'm here - a traditional conditioner/finish is dubbin - a basic mix of: Tallow, Beeswax, and oil or grease - you can start out at 1/3 each with oil for a softer grease type mix. For a stiffer mix try 30 parts tallow, 15 parts bees wax, and 5 parts oil.
For those who don't have access to tallow I have used a mix of 30 parts pure hog lard, 20 parts beeswax, and 5 parts Extra Virgin Olive oil or bear oil.
For a shinier finish add some more beeswax and cut the tallow/or lard a bit - be careful not to make it too stiff, but if so add more oil and lard/tallow.
In fact you can tweak the mix in various ways for various purposes and uses, but the recipes I noted above are a good place to start.
I heat and mix the whole thing in an old crock pot set just high enough to melt the beeswax - around 150-160° F is a good heat - you can go a little higher but don't burn it.
If you've got pine resin/rosin (fiddle rosin, etc or natural pine/spruce/hemlock/cedar sap or rosin) throw in a small chuck or two for a nice odor plus added anti-bacterial/anti-fungal properties.
