Hi Erich,
I think these are probably BA (British Association) threads including the choke grub screw.
I've tried to find some plated heads and they rarely surface, ordinary BA slotted round head machine screws are still easy enough to find though. It may be worth getting a small batch plated.
I bought most of my BA screws on eBay.

Size 2, 4, 6 and 8 are possibly the most commonly available.
