Mortised Cupboard Cabinet Door Lock, Key and Keyhole Cover

This little brass faced lock is stamped Made in Germany and I was only able to get it to work in the position shown (there are no keyhole openings on the other side).  It comes with the original ornate steel key and a tiny brass keyhole cover.  The price shown is less than what I would sell the key and keyhole cover for so the lock is considered free.

Lock face plate 1/2” x 2-3/4”
Lock body 1-1/2” x 1-7/8”
Lock bolt 13/16” x 5/32”
Face of lock to center of keyhole 31/32”
