Hello All,

Below are several links to photographs (and other scale data) and historical information on the Convair MX-774 Hiroc, which pioneered several technological innovations (pressure-rigidized "balloon" propellant tanks, a separable nose cone, and gimballed thrust chambers) that Convair later incorporated into the Atlas ICBM.

I have a couple of polyurethane resin duplicate Centuri PNC-89 nose cones from Sirius Rocketry's ( www.siriusrocketry.com ) "Moldin' Oldies" product line, the injection-molded (and later, blow-molded) originals of which were used in Centuri's MX-774 scale kit. Unfortunately, the scan of the die-cut balsa fin sheet on JimZ's web site ( http://www.spacemodeling.org/jimz/ka-3.htm ) doesn't have a scale to indicate the fin size.

Does anyone here have a .PDF scan of the Centuri MX-774 fin sheet or the fin dimensions (including the fin sheet thickness)? Many thanks in advance to anyone who can help, and here are the other MX-774 Hiroc links:
