MonoMonday: Metal

This is the key to my front door it is an old Chubb key and shows signs of forty odd years of wear and tear. I rather like the shape of the 'teeth', it's thick collar and its hexagonal head. I tried to have a copy cut of it several years ago but was told that they don't have the machines for cutting these type of keys any more. I'm hoping I don't lose it or it doesn't break in the lock any time soon as I shall have to have a complete new lock fitted.
