I have come across an old keepsake box that contains a strange lock that I can neither identify or pick (I've must've tried almost everything



It looks and feels like pretty cheap lock to be honest but that clasp is sealing the box shut well.
The hinges on the back of the box state the maker as CHENEY ENGLAND
I've seen Cheney locks before but not this style.
I have a slightly similar styled lock on a metal briefcase containing a poker set, but that has an easier design to pick.
Any help would be greatly appreciated!
