This stove was probably made in the early 1900's. (possibly could be August of 1884 since that is within the time frame of the company name. Prior to 1900, there was normally more scroll work and Victorian style) Could be right around 100 years old making it "antique" right now.
Incorporated in 1881 (succeeding Phillips, Buttorff & Company) and a long history of consolidating with and absorbing many businesses, Henry W. Buttorff started out as a sheet metal worker (tin knocker) and became a business mogul known nationally. Involved with steamboats, railroads, stoves, furniture, pottery, coal, real estate..... he had his hand in anything Tennessee.
Amazing history of this family and business starting with his Grandfather from Holland moving to PA where his father and himself were born.
