Ok, here are tube lengths from an open Centuri Argus kit:

Bottom tube: ST13 12"

Middle tube: ST8 5.5"

Top tube: ST7 7"


All your other callouts I think are correct. The Estes Yankee kit used a very similar 'looking' cone to the Centuri PNC-71 cone (used in this kit and, as you pointed out, the X-24 Bug kit and for the plastic pod cones on the Orion kit...and a few other kits), but it is not quite the same. I got some of the Estes cones about 10 years ago thinking I could use them for an Orion clone, but they just did not quite do it for me.

And as GH pointed out, the fin can is the original one developed for the Enerjet 1340 sounding rocket and used in quite a number of kits over the years. Wow, that fin can is approaching 50 years old.
