Dixie Gun Works does sell a number of accouterments - nipple wrenches, screwdrivers, flasks - those things that were commonly a part of a cased revolver.
They - along with S&S Firearms - also sell some original Civil War era 'brush and thong' bore cleaning 'equipment', as used with the various carbines of the time.
As to cleaning rods - you have to go further down the trail, time-wise - and then you begin to encounter 'barracks rods' and buttstock rods that were used by the Frontier Army, though Henry and Winchester both had screw-together rods.
If it's a 'Gun Cleaning Kit' that you're after - those don't start being offered until the big mail order houses catalog them in the latter 1880's.
Good Luck.
Vaya,
Scouts Out!
