Cadmium on the left.Reason being is that the left looks like the pictures i have of the booster on Steve's L78 little more silver than gold.

Our local plater made that change about 4 years ago.... both were Zinc dichromate? The new process is "more environmentally friendly". The new plating is very light and yellow versus the older.

Not sure if they still do Cadmium but at that time it was about double the price of the Zinc Dichromate. They generally only used the Cad for Aerospace parts and didn't like to plate dirty car parts in the cad tanks.

The oneon the right is the Correct Finish as OEM, Cyanide Cadium, the one on the left was done by someone else in yellow zinc. I hope Steve post picts of what it looks like up close.

They're both wrong.

My booster is the world standard for correct finish, and it doesn't look like either one of these. Mine is silver metallic paint, and don't try to tell me mine is wrong either, because I have proof.

I know mine is right because I bought it from a guy who took it off a rare car he bought on eBay. Yep, "RARE"...all upper case too, and I have a screenshot to prove it. Not only was my car marked RARE, which is really pretty much enough by itself, but also the original owner of my one-owner car was killed in Vietnam, so I KNOW it is correct. The guy I bought the car from said the guy who he bought it from said he had a newspaper article to prove it.

So both of these boosters are wrong. :noway: they're supposed to be silver
