well im not sure exactly how old? A brief description of details concludes, a clock of about 1 and a half feet in length from top to bottom, and about 1 foot from side to side. The top of the clock which is octagon in shape, holds the numbers from one to twelve and is about one foot in diameter around the octagon. The hands themselves are made of a black in color type of metal and and about 1 inck below dead center is a keyhole which "i believe" is for winding the clock? The key itself is made of brass and is about 1 inch in diameter. The clock has a faceplate in the shape of the octagon which holds the glass plate that covers the numbers and also opens. In the center of the numbers is the inscription " INGRAHAM ". At the top of the clock is a sticker that reads American Clock Company authorized dealers. The bottom base which also swings open is encased in glass with the inscription " REGULATOR " etched in the glass. Behind the glass is where the pendulam swings. The top octagon door glass is actually gone if that makes a difference ? Other than that its in great shape! Its light in weight and is made of wood which to me seems to be mahogany!
