Well the Lanier 33% has a 96 in WS and the 1/4 scale from them is 72 in. Doing some math yours at 82 in comes out to 28.472222% scale. Kind of an odd scale. Probably built such that folks could join the 80 inch club even though IMAA only requires 80 inches or at least 1/4 scale as their minimum.

I am now at a loss as to what you may have. I sudjest you tacke some detailed pictures of the plane and as good as possible pictures of the interior construction noting use of foam core and see if anyone else may recognize it's manufacturer. It is deffinately a Laser 200 though.
