San Miguel de Allende Roman Knockers

This is the only Roman Knocker I've seen that is forged from Iron!!!

Funny thing is about this little town there are so many different variations on the same design. How Many cast bronze hands are there in town? I've seen many but really no two are alike or from the same casting. I guess no one has ever saved a mold or a drawing so when the caster is asked by a client for another one they start again from scratch.
