These are great combination padlocks. They are large and heavy. They are intricately made. The combinations can be changed, as long as you have the current combination or the lock is currently unlocked.
This one is also in pretty good cindition. I can only guess that this is why the lock went for more than average.
This padlock had a high bid of $798.55 (Plus $10 Shipping).OFFERING THIS RARE ANTIQUE HEAVY BRASS COMBINATION LOCK MARKED CLARKE COMBINATION LOCK CO. BALTIMORE, MD.
