Rangeball,

That's right, the original is the one I use. I had the finer one, but it wasn't bright enough and didn't last as long either-at least it lost it's glow after a couple of years in my bow parts box.

Bob, that is close, actually looks pretty decent if you have that type of site. What you are looking at is tritium in a case, not a fiber optic illuminated by tritium-big difference in brightness, also pin size though.
