I am not sure the model of your safe, but they all had interesting names, like "The Sandwell" as well as other model names. Are you just trying to get an idea of what it is worth as an antique in case you were to sell it or trying to get a key made so you can use it or have it as working decoration?
You see the 2 screw holes above the handle? That's where the makers name plate would be affixed.
Here are some photos of a T. Withers & Sons safe from an auction, looks pretty spot on with the handle, the rose around the handle, the hinges, and the location and shape of the key hole cover:
