3 1/2" tall. Good condition. Steel body, brass wheels. While the combination can be changed by disassembling the lock and rearranging the wheels, the number on each wheel cannot be changed so there are only 3 possible combinations. With combo. - eBay
I would like to think that this lock when new came with additional wheels to increase the possible combinations from just three for each lock.
This combination padlock sold for $129.50 (Plus $6.95 shipping). That is a real decent price for an unassuming lock.
