I could probably sculpt and make someone a casting mold for those light lenses. Plaster or rubber mold. Looks like an easy fix and easy thing to sculpt.
I've been wanting to throw some of my casting knowledge at recreating bike parts. Just lookin for the right thing to do it on.
Hindsight, I could probably sculpt and make the mold for the whole tank. But you'd have to find a fiberglasser.
Meh. If anyone ever wants to collaborate on a cast of needed rare parts in general, get in touch, I've been mulling it over. If something inspires me, I'm game.
