This is a rare antique iron cash box and insert from the early 1900s; great collectible piece with original hollow barrel key. The interior is painted red. This antique box is a great display and collectible piece, ready to be restored should you choose to do so. It is very unusual to have the original key intact. It measures approximately 10" in width, 8" in depth and 4" in height; quite heavy weighing about 8.8 pounds. Please refer to the photos I have included as they are considered part of the description.
