Neither of them has been tested, so they are both being sold as is for parts, repair, restoration or display. Each measures approximately 10 inches long by 3 ½ inches wide by 3 inches tall. Both are very dirty and dusty throughout from years of storage in a garage and could use a good cleaning. Both show moderate to heavy surface scratching, scuffing, discoloration and wear throughout from age and use. The bottom hook shaped brackets show heavy to very heavy scratching, scuffing, tarnishing, pitting, surface flaking and wear throughout. The cords have some areas of electrical tape repair in a few places but are overall in fair to good condition.
