JimZ's site has a generic drawing of the fin pattern, but no measurement, and nothing to indicate that it's from an original pattern. I'm looking for a scan of the sheets with a ruler (for scale). Oh, and it's not the same as the Estes Astron Ranger (K-6). According to the Ranger's instructions, it uses the SP-6 pattern sheet. I need a scan of that too.

Based on the SP-6 pattern sheet found on JimZ's site, the Ranger would be 23.572" tall. However, the 1971 catalog states it's 24" tall.

Thanks!
Jim
