I believe part 211-C is the 13″ green striped pad for Oreck buffer (although picture is of regular green striped nobles buffer pads). Not a fan of the stair buffer, but currently no alternative I like better (big buffer or HWE). I do like the size of it, but I always know I have to follow it with a towel and lots of elbow grease, especially on the edges. All my pads are shredded, and now my plate has lost all of its teeth (just cones now) so it doesn’t hold pads very well if at all. Can we order a replacement plate? I searched the online catalogue for “plate” and the only one I found was titled “stair buffer drive plate”, but the picture was of the regular drive plate for a nobles/matador buffer (3705-C). Assuming it’s the one I want, but assuming hasn’t worked for me all the time when ordering.
