The four photos shown here are of this week's 'Mystery Object'. It was purchased at last week's Long Melford Antique Fair. It is a little under two inches long, and on a chain that is seven inches long.
Can you guess what it is, where and when it was made, and where the chain would hang. I think it would be only fair to add that it is made of polished iron/steel.
Good guessing regards, Mike.
