I have also been looking for a source for a piece of hood trim I would like for the top of my three piece 32 hood.

I have found my local industrial metal supply, to list "flat/oval" bar stock in a couple of different widths. It could be stainless, hard to drill/tap but easy to polish. Brass, easier to work, drill, tap for mounting but then you need to have it plated. Or, aluminum easy to work, drill, tap, and is easy to polish but would need a clear coat (powder or anodised) to keep it looking good.

I ran across a guy at the Los Angeles Roadster Show that makes custom trim and it was "very nice", polished aluminum.
