Looking for Coaly to help me determine if my stove is an imposter!

[jennifrick]

We bought a home with a wood stove and we would like to learn as much as possible about it! It says Fisher on the front, measures to be the grandpa bear size, has serial numbers inside each door, but no numbers on the back or bottom that I can locate. Any advice on where to look next to figure more out?
The picture of the bottom is pretty terrible, but it looks like there's an outline of something? I'm not sure what I'm looking at!

Anything inside doors are foundry marks, not serial numbers.

Serial Numbers are only on UL tags.

Pictures of the stove would help identify it, and the location where found.
