Sorry about missing your disclaimer that you weren't thinking about drilling the pedal eye area. As to the engraving, during the "drillium" era there was also a fad of "pantographing" components, i.e. engraving designs, logos, the maker's name, etc. and filling the engraved lines with contrasting colored paint. It made for a striking appearance but also led to a lot of broken parts (can you say "stress raiser"?) and quickly went out of fashion.
