Any one seen a Turbo Manifold like this one???

This appears to be similar to the old Accel adapter which went on top of a standard manifold. The thing had a pair of check valves connecting the carb chamber with the intake chamber, and allowed the carb to feed the intake directly at low RPM/ high vacuum

(It was not originated by Accel, but Turbo--somebody, LOL)
