If you will fill out the form below and hit the 'submit' button, I will help you identify your old key and give you some information concerning it's place in history.  Take a little time and look the key over thoroughly.  The slightest little detail can be a telltale sign.  Don't forget to look for markings or pencil marks on the underside.  I need the dimensions of the base to make a good ID!  Don't forget your email address. Without it I can't reply to you.

Look for a picture of you key in The Telegraph Office Photo Gallery  where you will find many photos of vintage keys with a short note.
