Depending on your 'skilz' it wouldn't be fiendishly difficult to replicate the original headstock plate, if it is indeed made how you describe.
A sheet of clear pickguard material, perspex or similar, cut to shape.
A gold waterslide decal (printed in mirror image), there's folks on ebay will make them for a tenner from an image. Apply decal to reverse of plate, then matt black aerosol (easier than gloss).
Flip it over and hey presto.
