From family estate. Measures 10.5" T x 13" W. Believe the back wood to be original, two parts hand groove fitting and the finish to be original as well. Prior to storing this clock (in the early 1990's) was on mantle in working order with original goldtone key. A jeweler friend provided the key shown in pictures, it fits one winding post but not the other (did not want to force) it does wind and when pendum weight on back is attached, hands move. One section of back has old Sessions Cl...ock Company label. I am leaving the back off in two parts for buyer to assemble. Cleaned lightly with polish purchased at Antique shop, more thorough cleaning will be left to expertise of buyer. I have provided all information I believe to be helpful, howver, if you have more, please feel free to email. From smoke free home.
