Bill Eichelberger's Semroc - Sigma II
| Manufacturer: | Semroc  | |
| Diameter: | 0.7550 inches | |
| Style: | Multi-Stage, Sport |
No plans exist that I know of, so I used the artist rendering in the 1970 Astronautic Modeler to come up with fin shapes and tube sizes. This is more of a close guess than an actual rocket built from a plan.
