I finally found out what the extra numbers in the bridge are. You know the ones that say 4-4 or 3-5 or have arrows up or down. These indicate the number of other sizes and colors available. If you knew this don't share, I've been trying to find out for years, and my reps and mfg's couldn't or wouldn't share.
The arrows indicate more sizes larger if pointing up, more smaller if pointing down.
Not quite as good as printing this on demo lenses in small but legible English, but a help in any event.
