The thin brass is not an inlay, it's an onlay or applique. As Paul stated, the finish is built up around it. Even if you can purchase the solitary "S" without having to but the whole applique, you will also be extremely lucky to remove the old letter without chipping the margins. Maybe applying heat with an iron (surface protected with a cloth) to the "S" will soften the glue and margins enough to limit damage. The whole area will then need to be sanded through the clear protective coat to make the color and patina make on the brass and a clear coat put over it all. If they want it all looking the same, remove all the other letters and leave the black silhouette. -- Regards, Jon Page
