sweep not working at all on this..

OK. Your biggest problem was as Michael pointed out.

Correct them first, then loft three curves using profiles and scaling curve. This gives you a close match
(now we need match Michael !!)...ok then sweep the surface as you did originally. Because you have kinks in the
curves it builds a polysurface which is rather handy....split that polysurface and also the first one and join together.

Hope that makes sense for a quickie ?
