Does anyone know what plane this is
 

I bought this plane at a swap meet an was wondering what plane this is.
The top wing is 57 an lower 48 inches.
It has a slight undercamber airfoil.
She had a os 40 fp on her but Ican't picture that engine flying her she wieghs about 8 lbs an has lot's of ply in her, I am now putting a 91 suprass on her
Also does anyone know how to find the cg since the lower wing is so much smaller

I don't have a clue to what it is, but it's a pretty little bipe! I agree, the .40 FP wouldn't even get it off the ground. 57" and 8 pounds, huh? The Surpass .91 sounds perfect for it.
