Thanks for the thorough post my man! Two quick questions, regarding the specs: Are we talking about the standard 19 top cap or the nzonic?
And the other thing is, about the top cap screws, I see you mentioned two. The atty pin is the 8/32 or the 3/16? Not sure why there are two screws? LOL

Brass screws are not difficult to find at all - many hardware stores carry them, but Copper screws are very difficult to find because they are generally too soft to retain their threads....however, they are used in tattoo machines because they are such good electrical conductors...here are some on eBay that may work for you:

If you can't find the exact thread size - go just a tad larger and let the screw cut new threads. Delrin is pretty soft, but still takes threading pretty.
Good luck...
BTW - the specs for the #19 are:
The top cap screw is 3/16-24 or #10-24
The bottom switch screw is 1/4 by 28 (I couldn't find this one in brass but I'm sure if you search around you can find one.)
Remove top spring and replaced with 8/32 brass screw.
