Any experts on old stairs?

[Lake Chuck Duck]

Been having this old spiral staircase for years and it has always just been in the back yard. A long time ago there was an apartment complex across from the memorial hospital in lake charles. They tore it down to build a parking lot. My dad was working at the hospital at the time and he went and got the staircase (which was the fire escape stairs). It is still in great shape. If it were just blasted and painted it would look great in someones home or camp, maybe even deer stand.

I was looking for opinions on what this thing may be worth, will be looking to get rid of it soon.
