All I can say is WOW! look at the price this Treasury padlock sold for. Well over twice what I paid for mine.
Rare 1876 Brass Clarke Combination US Treasury Dept Lock w/Code Superb Piece! Super Nice estate find. One of the toughest early Brass Combination locks to come by, especially the US Treasury marked ones. This one is in excellent condition with nice even patina and includes the combination! Don't pass up this chance at a stunning original lock! Nice addition to your collection. - eBay (14 August 2013)
