I have a question regarding a pair of what I believe to be antique knuckle dusters. I was wondering if any you could perhaps shed some light on them for me, as far as how old you think they are, and if they're legitimate of course? They appear to be late 1800s, early 1900s to me, but I'm no expert. I've only been able to find a similar example on one website. I'll attach the link below. They appear to belong to the Queensland police museum. Well, any input on them is greatly appreciated.
