This kakesuzuri style ship’s chest, or funa dansu, was locked when the client purchased it at auction.
I removed the lock to access the interior wherein I found two original keys. The secret box found behind the lower interior drawers was missing, so I fashioned one out of kiri. All locks were cleaned and re-affixed.
There was some bug damage and wood restoration needed for a chest this old, circa 1850-1880, but it is a fine specimen of tansu craftsmanship.
