These 7 old locks were purchased in the early 60's in Chandni Chowk Delhi which is one of the oldest marketplaces in India from the 17th century. One lock has working key. The top middle lock measures 2 1/2" wide x 3" and is a special handmade trick lock with a secret way of opening from the bottom...but...you'll have to figure it out! They all have rust - see photos. Kids LOVE these 'curiousitys' and they look cook on a table by the candy dish! All could use a good cleaning / dusting
