I recently bought a home an inherited a wood burning fireplace insert

[Macfamily]

Can anyone help me identify the brand of this fireplace insert? It has a brick lined tilted back fire box, single door with a handle on each side one is fake the other latches the door, it has a rectangular glass window with gold screening, the dual blowers are located across the bottom below a significant bent plate steel shelf. The heated air blows out each side also covered with gold screen. The damper is controled bt two brass pulls located on either side, the fire box air control is located under the window on the door. The construction is sheet steel and a cast iron door. I think this unit was made in the 1970's.
Thank you,
Joe
