I picked up a really nice original 1957 WH6A Wizard Super 5. A few interesting things: SN wise, it is definitely a wh-6a but it is missing the "A" in the stamped model number. It is also consistent parts book wise with a WH6A. It has as a smooth propshaft with shear/drive pin for the prop. I was unaware of this feature. As far as can be seen with the parts book, they went with this design for the 6A. I guess they got sick of dealing with prop clutch issues.
found - '56 wizard super 5. getting ready to do research. but I am no engine guy and do not want to erase any value. This thing is about a 6-9/10?
