I also have another question. By the way, beautiful job with this!! I would love to bring my model 65 convertible to you and see what you could do with the warped motor head. I know, can't fix that on that model and everyone has that problem. Anyhow, my question is this. The owner claimed that she loved the dusting tools. Was the suction on that particular design, with attachments, better than on later "convertible" models? I have always looked at model 28 and the early 61- 64 models from afar and wondered if that side tool conversion approach was better than the convertible's
