Black and Decker Delux Finishing Sander U-66 in perfect working condition. Made in Canada in early 1960's and could operate on AC or DC. Sold for a whopping $49.95 in 1961. It was my grandfathers and he purchased this new. Specs: AC or DC 115v 2.5 amp 4200 rpm "3/16" sanding orbits per minute. 40 square inch area, king sized power sander with 50% larger sanding surface" are some of the highlights from the ad we saw from 1961. Pretty funny what they wrote back then. Would make a great addition to any Black and Decker collection or anyone that wants a well built sander that will last.
