The NCR 8" nose cone is not common. Not sure what ever happened to the mold for it. It was not precisely the shape of a a Goblin nose cone, but not many 8" gone around back then. I actually have two of the NCR 8" cones. One good one that came with the kit I got from Matt and one that is slightly out of round and a few thousands bigger on the shoulder that came from a later mold.
The kit body tube was basically a peeled sono-tube in appearance. No Glassine.
Still mulling over whether to glass mine and paint it nicely, or do a little filling and sealing on the tube and Monokote the tube and fins and only paint the nose cone.
I did make new centering rings for a 75mm motor tube......

First flight will be on a 54mm motor, a K550, likely for my L2 cert, with later potential for some interesting L and M motors.
Busy week this week, but will have you some info by the weekend.
