Yeah, that’s an old Fichet lever lock an M2B or M3B. Theyre a popular French lock. Just type Fichet into YouTube or Lock noob 8 lever safe lock he has a great video taking a very similar model apart, different but the same mechanism. The work like a Lever lock but the levers are spaced radially and are pushed down. Edit. Even without the key you could sell it on eBay to the locksport crowd.
