Maybe the holster you are looking for is a 'Civil War' Confederate (brown) flap-style holster. Many offer this one for around $40 - Cabellas, Dixie Gun Works, just to name a few.

A military flap holster will do just what you are asking for - they protect the revolver from dirt, water and scratches. I've used these for years for an 1858 Remington (replica) as well as a Colt Cavalry with a 7" barrel, and they are very utilitarian. The one for my Colt is a black holster and right handed.

Because you want a brown holster, the Confederate holster is the right color. The Union holster was black. They were usually worn left-handed, so the soldier could use his right hand to control his mount, and drawn and fire with the left hand. A 'CS' buckel and brown leather waist belt would go good with that holster. I would'nt store any pistol in a holster - that will promote rust.
