[Boatanchors] RBM-5 screws, washers

The BC-611 uses #5-40 to secure the rubber PTT cover and bezel.  How many do you need and which of the four kinds of common washers does it use (flat and three kinds of lock)?

#5-40 is uncommon today.  McMaster has them down to 3/16" length in SS but you would have to I guess use a black Marks-a-lot on them.  The only black oxide finish screws that they carry are all socket head.

Somewhere, somehow, I misplaced the black screws & washers for securing the cover to the chassis. �Does anyone know where I can obtain correct-looking replacements? �I think they're 5-40 pitch & 1/8 or 3/16 depth.
Thanks!
