Antique Tin Dollhouse Dry deals Sink with Dishes

This little tin dry-sink is 4 1/2 inches long 2 1/4 inches wide and 3 inches tall. The lid lifts. There is deals a small chain hanging from the front but we're not sure why. Most of the blue lithography has been chipped off along with the ecru colored paint. The little dishes are adorable. There are eleven pieces, two unmatched. It is especially cute and I think a child had a lot of fun with it. It was probably made in Germany and is a unique piece.
There is one loose leg and I've shown a picture of it.
