I don't know if this is a new style of LRI or not but have sent info and these pictures to Steve Bobb for his insight. The person I bought this from said it was mounted on the side of a barn in Kansas and had a square or star shaped rod through it. Unfortunatly they had no more info or a picture of the system in use. Judging by the quality of porcelain, I'm thinking maybe 30's or 40's manufacture.
