Wandering through the Centuri 1972 catalog, I came across three "non-kitted" designs on page 54. I had worked them up in the original sizes back in September 2005.

Since we all know I *can't* leave well enough alone , and now that the Semroc Nose Cone Designer is up and running, I took a crack at upscaling the middle ST-8 and -10 design slightly.

I noticed that ST-8 and -10 upscale by 1.29X to ST-11 and 13. The slightly bigger version turned in some pretty good performances. So while I don't have an official name for it, I call it the "0810" design, referring to the original body tube sizes.

I'll post the nose cone and reducer/transition files separately.
