Most of Continental (Austrian and German) sugar boxes made in 19th century had locks.
They were made of iron, fitting into a small compartment closed with a small removable gilded silver plate. As iron rusts and the silver is often cleaned, small silver plate should be removed from time to time and the lock cleaned with neutral oil and rust deposits removed from silver. Sugar boxes are often found without their locks because iron rusts and deteriorates easily; nevertheless, one can be lucky to find one, and because they are actually not attached to silver they can be easily inserted, if fitting, into the compartment.
