SU Carburettors Damper Tops - HD8 verses HD6

Otto the BLACK plastic tops came in later than the period in question. They are the replacement parts one gets now but not correct for an early car--but then you did not say how early.

........then again, my HD-8's had black damper tops, correct for this set, off an early XKE, I was told. Now bolted to a straight port head on my 3.4L, XK-150.

see link below for photos of the complete rebuild & an image of damper tops.

I was questioned on my 63 XKE this last weekend on my dampeners as mine are plated. It was mentioned that most all they had seen were brass colored.

Thank you gentlemen. I appreciate the quick response and we all agree. I wanted to be sure that the tops were plated.

Bob what do I say ---nothing. But Skinner Union and Jaguar agreed that they were Brass with Cadmium plating. I thought we had dismissed this as everyone that was questioning the finish drawings had taken their tops and seen that in the areas you can not polish there was in fact the remainder of the cad. plate. In case this becomes an argument about an E type or a MK1 (which I assume to be either a 2.4 or 3.4 L saloon) I have the finish drawings for that too--guess what--Brass with Cad. plate on all parts you have cited. Nigel is a good author but he is just documenting what he has seen--he is right --they are Brass--but after 50 years or so cad-has left the building.

Out of curiosity from what sourse did Nigel obtain his information? We do know trom an S.U. Carburetter Co, Ltd drawing of the various finishes on the HD8's used on the 1958 XK 150S states" All exterior brass and steel parts(except throttle spindles & accel needle) to be cadmium coated". George, What say you?
