Hi all. Trying to help my brother identify the manufacturer of his snowblower which our dad bought when we were kids. Purchased around 1969 or 1970 in northwestern Wisconsin. Its 78 inches, and my brother seems to recall it being painted yellow originally. Have not found any tags or markings on it, but it has been repainted a few times. Probably a long shot, but thought I would put it out there. The wooden box is obviously an add-on. Thanks.
