to me, the red and black saw has some homelite like features.. like an XL-12 similar intake (straight in to a black manifold, then the 90deg turn to the crank case) i dont see any brand/model labels left on it, no stampings i can find.. thing is neat, but its hard to find a clutch and cover for a saw you have no clue about! lol. design is kinda cool. i was thinking jonsered but i cant find any similar to this thing.. and they usually have the metal badge.. this seems to have had stickers only
