These are Original Head & Manifold Gasket sets for de-carbonising, or [ de-coking ] the Top End of the Engine. Contents as shown. They are for DISPLAY ONLY, as they are 60+ years old. They were Distributed by NASCO as part of the HOLDEN SPARE PARTS DEPT. They are for the VAUXHALL 27 HP E MODEL Part No. Z27036. [ I thought maybe the CRESTA, but that's only my guess].
These were originally sold for 2 pound, 13 & 6 pence!! You can have the pr. for $40 + post. I will pack them to avoid damage in transit. You can calculate the Inflation Rate.
