[EDIT: Moved to Questions from the Public - This Old Safe]
Could you post another pic zoomed out so we can see the entire safe door? The hinges and square or round corners often tell who the maker was, age, and typ of lock inside.
A ruler in the photo or a coin or common item for scale would be helpful as well.
Your keyhole has paint on the left of it, so it's actually wider than the current hole.
I fixed your pic as well, the [image] commands only work if your imgur link is to the exact picture not just to imgur's page where the pic is embedded. Right click the pic, click View Image and that will show you the
http://i.imgur.com/picname.jpg path the [image] command needs to display the pic.
Also, please let us know where you are located, we have members in all the English speaking nations, and knowing where the safe is located may help ID the manufacturer.
Thank you,
