Yep, that is one of the Cox TD 09's and it's all factory stock. I'm not sure what their value is, but as Jason_WI said, they had a limited production run over 2 years, so it is quite rare.
Cox actually produced a small pattern plane for this engine called the Scorpion. Wood fuselage, foam core wing.
