Generally inserts are inserts and free standing is free standing. There is no invetween.
As far as ID and info, you most likely will not find much. Looks to be one of the thousands of off brand plate steel stoves from the 80s.
With most stove manufacturers there is no “in-between” or cross-over type stoves. “Generally” that is the case. However there were and still are exceptions to that “general” rule that are still currently being made.
Buck Stoves …
Currently there are several models of Buck “wood stoves” that can be used as “freestanding” or as an “insert”, just by removing the legs and getting the proper factory insert trim packages sold from the factory to be used when an insert is being called for, as they have removable legs and they are designed to be both.
Hitzer …
Currently the Hitzer 983 “coal stove”, previously advertised as a “wood/coal stove” (still the exact same stove….only the way it is advertised has changed because of EPA regulations), is still offered as a “freestanding” unit or an “insert”, as it also has removable legs and they are designed to be both.
Brunco …
I believe is out of business.
The stove you are looking at to buy is a “dual fuel” stove or “coal/wood” stove as they were advertised.
Let me point out some details and differences that I am seeing of the stove you are looking at. I’ll give you a link with pictures to try and explain the differences that I am seeing.
I am not 100% sure, but I believe based on the picture in the link I will provide that the unit you’re looking at is actually a “freestanding stove” model with removable legs (legs removed) that has simply been piped into a fireplace and a trim covering was likely fabricated to make it look like an insert possibly having a liner go all the way from the stove to the chimney top. They likely chose this “freestanding” style with removable legs because they had enough room on the hearth and they he unit would also provide more heat into the room with using a blower fan to get heat into the room.
If you notice in your picture the stove is deep with a side loading door. An actual insert doesn’t have the side loading door. I will show you in a link the stove portion in front of the trim shield isn’t nearly as deep and it also does NOT have the side loading door.
Study the pictures in th link below at will better explain the stove you are looking at to buy as well as show the differences.
