You're in the right place. Welcome to TF!
I was considering replacing mine once upon a time and called the Marshalls at Navigator Yachts, speaking to Gil Marshall and the plant foreman (Juan?) who was with them building the Californians back in the day. He told me they were not being made and, in essence, they had become as rare as hens teeth.
I've never seen one up close. Anyone have any pictures? Were they 3D or were they just a flat panel? If they were 3D with relief and texture then a sand casting sort of thing could be done if I had one.
I think most of that stuff back then was done with a casting. Most of the boat nameplates I am aware of were done that way.
Thanks!
Check ebay. There are replica stickers for sale there.
I'll take a closer look when I'm aboard next week. I'll try to get some good photos.
Why not see if anyone has one in good condition, scan it and then 3-D print as many copies as you want. Paint or plate as desired.
You could also print it with a low melting point material and use it to cast metal copies using the lost wax process. A good foundry may be able to handle the whole process........
