What do you think of my idea of going back to square one with one of the other KCS28 chassis I have and resurrecting it on mostly original components?

Can you get a signal thru at 22MHz? If so then the trap is attenuating. Because you offset the stagger tuned stages, likely there is less gain around 21.25MHz.
Tell us if you get anything at 22, 23 or 24MHz. If so, you are not getting sufficient signal thru at 21.25MHz. raise the signal and reduce the bias from -4.5v. adjust the pot until you get a signal.
How are you injecting the RF out from the HP8601a?
