Steve at Thunderbuckerranch.com makes these, they're solid nickel silver. He made exact vintage copies from a set of mine. Also does them to fit later TBirds and various Epis which have different width center sections. Email him for pricing. BTW Stjofon, your guy might be able to get nickel silver.
