View attachment 979835gobsauce, Mobil1 grease (it's an all purpose synthetic chassis lube, red in color). It's temp. range is -35° to + 350° F so it won't get runny/messy. You see the wide and deep forward most groove on the arbor. That is the fouling groove. This revolver was made in 1863.

Now that's class. That looks like an original antique 1860 Colt frame to me.
And I just learned something. The arbors on my Pietta 1860 Armies don't have such a nice deep fouling groove. You can also see in this photo the attempt I made at cutting fouling grooves on a 1858 Remington cylinder pin. Not very effective. I wipe off the cylinder of my cartridge conversion 1858 after every cylinder full of Black Powder ammo. I will have to try 45 Dragoons's modification.
My original Colt Richards Conversion does have a nice deep fouling groove on the arbor. If I ever get around to shooting it that will probably be a big help to keep it from binding.
Regarding lube, I have always used Ballistol. Bore butter has worked in the past too. I do know a couple of guys who use the Mobile red grease. They swear by it, I just don't like the appearance. But that's just me.
