RE: Wanna make mold of this cowl, how?
Relieve foam from the inside and install a smooth disc faired into the nose ring. Plug has to be slick. Paint it, wax it, stick it to a parting board, Klean-Klay the plug to board junction, apply mold release, lay on the resin and cloth, wait for proper cure, remove parting board and then pop plug from mold. The plug looks like it may have to be made in at least two parts for it appears the mid section circumference is slightly larger than the aft end's circumference. Even if it is a perfect cylinder it would need to be made in two parts. You need a certain amount of 'relief angle' from the parting board in order to create a one piece mold.I have a tutorial on RCScalebuilder. I made a cowl for a 1/4 DH-5 which is in 'scratchbuilds'.
