the nicest finish is to blast or tumble with walnut shells
if you bead blast or use harsh chemicals it will dull the shiny aluminum finish.
It should be an M-21 and the correct stamp for that is "FT" and is in yellow 1 inch high block letters.
You can buy stencils,but I choose to have a rubber stamp made so I have it for future uses.
