This is a picture of the Union calendar image, which we framed a few years back, and now graces the office wall.

The description reads – ‘Brass Padlock, English, 19th Century. A high security fitting. Eight levers. Designed to Foreign Office specification for locking diplomatic bags. Josiah Parkes Collection’.
Hopefully other members/visitors/collectors can add to this thread with other versions of their seal padlocks.
