Default Astrobee 350 fins "fix?"

Hello All,

Having had an original Semroc “Retro-Repro” Centuri Astrobee 350 kit (which the new Semroc also offers, see: http://www.erockets.biz/semroc-flyi...t-astrobee-350/ ), comparing it with the original Centuri kit (see: http://modelrocketbuilding.blogspot...erobee-350.html and http://modelrocketbuilding.blogspot...erobee-350.html ), it is obvious that the Semroc kit’s fins are—for whatever reason—down-scaled from the fins of the otherwise-identical Centuri Astrobee 350 (which Centuri also called “Aerobee 350”; here’s an older catalog view: http://www.ninfinger.org/rockets/ca...i68/68cen8.html [later, the kit was updated with a plastic nose cone, see: http://www.ninfinger.org/rockets/no...a/72cen022.html and <in a photograph> http://www.ninfinger.org/rockets/no...a/72cen012.html ]). Also:

Does anyone have a correct fin pattern (or dimensions) for the Centuri Astrobee 350 fins, that kit's body tube length (the Semroc kit, with its smaller fins, might [or might not] have a slightly longer body tube), and the Centuri part numbers of its balsa--and later, plastic--nose cones? The plastic nose cone of the Estes Dragonite (see: http://www.estesrockets.com/rockets...169-dragonitetm ) may be the same size and shape (plus, the Centuri Arcon and Arcon-Hi [and their Semroc reproductions] may use the same balsa nose cone as the Centuri & Semroc Astrobee 350; if so, the Dragonite's nose cone might be a plastic "drop-in" replacement for all three kits' balsa nose cones).

Many thanks in advance to anyone who can help!
