SKIL Model 7200, 2-speed, Corded, Corner Detail Power Sander. I purchased this to help refinish my grandmothers preserve cabinet. I may have occasionally used it on other projects. Mostly it has sat in a drawer.  Triangular head. Sandpaper attaches to head with hook and loop. I'm also including a couple of partial packages of sandpaper. 150 grit and 240 grit. Sander works great. There is some minor wear to the edges of the head where the sandpaper attaches. It has been cleaned but there is still visible sawdust in the nook and crannies. It has a port to attach a bag for catching sawdust. From a non-smoking home.
