I have some General Tools Co. stainless-steel rulers that I've had for
a "few" years, #1251, HO/S/O scales & #651 HO/O scales.
The black "paint" in of some of the recessed numbers has disappeared
What is a best way to re-blacken these recessed areas in the stainless-
steel? (Short of just buying a new "General Co." ruler.)
I have nostalgic reasons for repairing and retaining them if possible.
They are the only ones I've ever used for building STMFC era cars.
Thanks, Paul Hillman
