Can't be sure until you count bricks on the sides. It SHOULD be a Fisher Fireplace Insert, but the legs could be cut off a Grandma with step top installed into the fireplace. You can tell looking inside at the "roof" if it is flat from front to rear. The Insert has no step top. The Insert should have a chain or lever controlled damper on the right. Can't tell in your pictures.
If it's an Insert, it's not a stove.
I don't see the required deflector above the air slot at top that directs heat away from mantle.
The Insert will have a slot on the bottom under ash fender for blower to push air in below the firebox, up the back, around the outlet at top and out the top slot. This is convection heat from the firebox directly vented into the room instead of radiant heat radiating into hearth to be extracted by your blower which is much less efficient.

You can still get the spring coil handles you're missing from Woodman's Parts Plus nickel (silver) or brass plated.
Below is a typical full size Insert with blower; This one was black and has hand painted doors that were not original.
