It looks to me like the number is 2130 (and one more number, of course), but I’d be happy to be proved wrong  |
Bead blast the area fine a fine grit 100-120 and just enough pressure to knock off all the clutter of paint and primer that working the area with a wire wheel just makes a confusing mess. If you cannot get in there with a small hand held media gun, chemically remove the paint scale, once the surface is bright (paint free) run a black wax crayon over the stamping to back fill then, or do a paper rubbing. I have had some great results going the black crayon route, but you need to prep and clean the areas better to make things pop. Oblique lighting with the brightest light possible yields great results, but if the stamping are not there (light struck) then they are just plain not there.
