Does anyone have or still make the nose cone or shoe to make an early 2,3, or Sternpower drive into a crescent shape?

does it look like this stuff?

My lower looks like the one on the right. I don't remember where I saw it but someone had a shoe type nosecone or the upper part of a nosecone without the pointy part that would blend the shape to look like a crecent style #3A 5 or #6 lower.
Crecent = Speed.

I have the old one also...I have been told that it is a totally different lower, i dont think they make a piece to change it over.....

I am thinking that these drives work great up to 5 deg pos trim but would benefit from a crescent shape at 5 to 10 deg that the single V's need to carry the bow. Guess I will start calling the Nosecone manufacturers one by one.
