Hello, I am looking for information on this pendant. I think that it is a Hohenzollern coat of arms because it has the same shield, crown and banner. Can anyone provide more information on something like this, such as when it could have been made and if it has value. It was found in a box of my grandad's old things including his army records. I am not sure how he came to have it but he was in the British Army of The Rhine just after WW2 and was in Western Germany. Thank you.
