Brass Chinese Koi Shaped Locks

These great circa 1950s heavy brass Chinese koi-shaped locks are ideal for holding closed a Chinese chest, but are also great objects hung on the wall or just sitting around. The larger of the two opens and closes without a key; the smaller (which I am just throwing in with the other) is locked and would need a Chinese key (which looks like a large, flat metal pin and are fairly easily found) to open.

The larger of the two measures 6" long x 3 5/8" tall x 5/8" deep. The smaller 3 1/2" x 2"x 1/2".
