Jay-

As far as I can tell, the SST main cone was always the pointy PNC-106. I have a first issue SST kit and the instructions and main cone are the pointy PNC-106 cone. That is also the same cone in the attached TIFF file in your message; I guess that is the same parts scan image from the JimZ plans.

My comments on the balsa to plastic change was on the Astro-1 kit that raeford was talking about. Pretty sure the SST started off with a plastic cone and stayed that way throughout (the SST was first released in the 1971 catalog, the same catalog that first carried plastic cones by Centuri).

Hope that clarifies my comments. GREAT job on the list by the way!!
