Vintage Japanese Tansu Chest of Drawers in Black Lacquer

Condition is pretty good structurally: it's solid and the drawers work ok (if slightly stiff..time in a heated house will likely improve that, but it's not bad anyway). A slight split in the backboard. There are no keys. The bottom lock is stuck and the catch has been cut so the drawer can open (see pics). The top one can be operated with the knob, if it accidentally locks. Cosmetically there are various scuffs and dings to the finish though not a lot really. The inside is pretty clean.
