Found this one hiding in with that unusual dual control lock I posted recently.
The precision in these is quite surprising for a lower level mass produced lock, the tolerances are pretty tight with 6 nicely fitting levers including monitor and a beautifully smooth action to lock and unlock.

Also hiding was this WonderBox mini safe made by a Spanish company back in the 90s, in fact I think they might still be making similar. These also have a hidden surprise in that the whole door, lock plug and the body are completely case hardened.
