Edwin Cotterill’s padlocks are amongst the most prized by collectors and the fantatically named Climax Detector lock is a rarity. This is a really big, extremely sturdy and heavy one – it is just over 5 inches tall and has makers marks, numbers and the pronouncement that the lock is “unpickable and powderproof”. The lock is working and has the original key. The lock is really well worn from heavy usage. The escutcheon that would have covered the keyhole is missing and it has some dings and small dents. There is a couple of millimeters play in the hasp but it locks completely solidly. The key is a bit corroded but you can still make out “climax detector”. - eBay (1 Nov 2009)
