That has Grandma Bear doors that is unlisted, no baffle, no shields. A few hundred at best.

I call them a wide body Grandma since drawings call for 25 1/2 inch wide top plate. Grandpa is 29 1/2. I can assure you they are Grandma doors on a wider than usual stove body. Note the faceplate width showing on front, and very little space between trees at door center. Grandpa has a much larger space between trees. The screen and door opening is Grandma size to fit the doors. 17 wide X 10 1/2 high. That screen is a #75-200-1 Contemporary.

Grandpa door opening is 21 wide X 11 high. # 75-200. They look huge compared to the Grandma screen shown.

They have their place where big heat is needed, but nowhere near as efficient as EPA Certified models.

Prices can be high for the rare collectable models. The highest I paid was $1000 for an unfired, new XL with Sun doors, from California with air freight, over 10 years ago. I have seen that model sell for $3000 reconditioned. “The Flame” or TF-88 that only 50 stoves and 50 Inserts were made in Georgia is another very valuable model.

Most sellers have no idea what they have.
