That one MIGHT be a sears "feilder" its got the chrome wheels etc.. If you go look at it check out the tag on the engine plate (back right side) If it was the feilder it will say sears on it.
It is a Tec (HS40) and its got the cool extended dipstick that is correct for the slanted engine on it (and was correct for the bird built bikes like that) in the mid 1970's
