Factory, I think that is what this trimmer looked like. Did some more scrounging in the other shop this af'noon for a Stover engine ring set and found the other aluminum tube, which is the fuel tank! I guess I have more to this than I had thought. It's been around here for 35 years or so and I never paid much attention to it. I'm thinking my son tore it apart in the mid 90's. I don't remember it ever having the cutter head, cover or shield though.
