Powered by a Magic Motor. In my version I have just fitted the Flexible Plates friction held by the Nuts on the frame. I needed 8 extra Washers to space the Pulleys from the chassis so the Set Screws do not foul on the Bolts holding the Trunnions and Fishplates. I also used a Cord Anchoring Spring on the winding shaft to hold the Cord and to act as a collar. Note: this model did not appear in the 1945-1947 manuals.
