Newly Restored Sessions Clock Works in Custom Clock

My mom purchased this clock around 1970 in CT I think. The case is a one of a kind wrought iron standing clock --- very heavy. The body used to have the same material as the rest of the clock and was lit from behind as the top is now. The works are an early 20th century Sessions Mantle Clock with a Westminster Chime. The clock is now in full working and chiming order and sounds beautiful I'd love to identify the exact clock the works are from and see if anyone knows anything about the casing.
