Don't see those very often anymore. Thinking GM used those with the internal breather canister from about 1960-1964 or 65. Then GM and other mfgs. started using the PCV system for crankcase ventilation. To the right person doing an early 60s build in original used condition, thinking maybe $40-45 for a good set, restored with nice paint, $60-$75 maybe. Limited market but don't see them a lot at all now days.
