Rock-A-Chute Mark II Nose Cone

I'm wanting to build a semi-clone of the classic Rock-A-Chute Mark II rocket as originally sold by Model Missiles back in the 50s.  I found JackHydrazine's excellently designed, excellently researched nose cone models here:

I found the cone ever-so-slightly too small, and while I was scaling it up a bit to fit the BT-50 tube I'm using better I also changed the base/shoulder area to my preferred style.

I take no credit whatsoever for this design.  Jack did the research.  I'm just sharing my version for others who prefer a one-piece model.  I highly recommend reviewing Jack's notes on his model for more information.
