Well I am USELESS with the plated plastic one but I have been looking at your plea for help and thought I would chime in.
I bought a used Hartzell 2295-P like this one:

Mine was cheap, used a kindah scratched. This one is new and shiny! They sell for more than 2 large new!!!
I think I will have to build up the top of the cowl about a half an inch in order for it to look right but I am not sure. I will know more this summer when I fit the prop onto the project.
I think it should look good!
