Our friend from Finland, Star63 was looking for information on restoration of a hood badge or some experience from people who have done it. I found 5 places that do this, and certainly there are more.
By the way, just as point of reference--Ford does not get into the manufacture or distribution of old parts for old cars. However, there is a huge business in doing so. Ford licenses the products with the logo on them. Products have to pass muster for quality and performance, and a license will be issued--probably at a reasonable price. Then, the manufacturer must make the product, sell and distribute the product too, and some license fee goes back to Ford. Ford has no investment in the project; they just collect money.
And with that, we have commonly available enamel badges for a early Fords (there appears to be hundreds of styles) running around $35-$55. Made and sold my and independent under license. Data plates, all manner of logo emblazoned trim, badges, etc. all in the same price range. I'm sure the same business plan is in place at GM. So, with those prices and the non-trivial cost of manufacture, I'd imagine the license fee is pretty reasonable. Just a guess...
