I am no expert on these locks but the keyhole cover has a serious red flag…….it is not uniform to the rest of the lock and it looks like it was worked on. In my opinion, it looks like a fake. I see faked locks and restraints all the time and I am suspicious of anything that says Colt, Winchester, Yuma, Folsom, Alcatraz, Sing Sing, Wells Fargo, B&O, Keen Kutter, and any other high profile names; I never give these the benefit of the doubt and for good reason. The fakers are getting a lot better at what they do and these fakes are getting very hard to spot. Just my thoughts.
