Will a balance staff for a 4992B work in a 3992B? Will a staff for a 992B work for either one?
Thanks, Jack Williams

Hello , yes a B staff works for the 992B, 3992B, 4992B and 950B, only the earlier E ones are different, [when they introduced the B models they were completely new] if you need anymore help just let me know..thanks

Paul, Thank You very much!
