@yeti42 , if you send me your plates I can install finger lifts for you. If you check out my system page you will see a Schroder CB that has a finger lift. I made that one.
Also, it is not a good idea to leave the finger lift lever up. That leaves the internal spring in the stretched position and it might weaken over time.
I hardly ever use the finger lift. I cue the record by hand and have an auto lifer at the end. I would think that the lever position should be an adequate "flag." You can always paint it international orange:)
