I had some left over brass 16340 caps and non locking brass buttons and just didn't know what to do with them, so i whipped them onto some stainless steel 16340 bodies, put a satin surface prep on them and threw in Rhodium contacts to boot! These are a "scratch and dent" lot. You know the drill, a few minor blems here and there, perhaps a bit of coencentric "ghost" ringing on them, but they are hardly noticeable. Note: These are Brass caps and Brass tarnishes, be prepared to polish frequently (don't polish the Rhodium plated switch contact or Rhodium plated top post contact though!)
