This big brass key is from the western reaches of the Pennsylvania Railroad, which by 1882 had become the largest railroad (by traffic and revenue), the largest transportation enterprise, and the largest corporation in the world, with a budget surpassed only by the United States government.
Its stamped C K on one side of the bow with serial number 3703 in between the letters identifies this key as having been made for and used by the Central Region / Cleveland (Ohio) Division of the Pennsylvania Railroad. There is no maker mark (there was usually a PRR on the opposite side of the bow, but not always), but collectors will recognize the big, thick bitted heavy shape used throughout the Pennsy's divisions.
Condition is excellent with no abuse and rounded bit and barrel edges clearly documenting service use. The color is terrific and darkening appealingly. The stamped marking is all legible but there is some light scuffing and some light wear, especially over the 03K .
Our information is that this marking style should mean that this is one of the earlier Division keys, with were made with a large serif style Letter-Number-Letter in an arc shape over the top of the bow.
