There was another one of these locks recently put up for auction:
Vintage KARCO Combination Lock
This combination lock sold for $44.99 (Plus $5.35 Shipping).
This is the oldest combination lock I have seen. I purchased it from an estate auction earlier today and was just fascinated. It is about 3 inches tall, 2 inches across and just over an inch thick. It is marked KARCO across the top of the hasp. Someone scratched the number 686 on the hasp and it may be the combination but I cannot seem to figure out how to make it open. Just an intriguing old lock.
