Knecht/Zenith Air cleaner cover clamps ?
Just curious as to what's the original finish as to the cover clip clamps on the round Knecht air cleaner covers. I see a number of them silver Cad or Zinc plated, but I tend to see more of them just painted Black as the air cleaners themselves are.
I'm specifically talking about the small wire cover clamps and not the large round clamps that hold the air cleaner to the carburetor.
I'm restoring some three clip 59 S Knecht air filters and just wanted to reach out to the group.
Thanks

Jim:
This picture is from the factory in about 1962 or early 1963. I found it on the web years ago, wish I knew who should get the credit for it.

The ones on my 1964 coupe appear to have a zinc finish but after almost 60 years, it's kinda hard to tell. I do know that they are not colored black.

Re: Knecht/Zenith Air cleaner cover clamps ?
Keeping in mind that pieces originally yellow zinc (#2 gold iridescent), will, over time lose the yellow chromate and become "silver" as if they were originally plated #1 zinc. This is a common error in replating brake calipers. Customers specify #1 zinc because that is what their aged calipers look like they were originally plated. Split your "silver" calipers and you will probably see gold iridescent on the surfaces that were mated. My understanding is that ATE plated all Porche calipers #2 from the beginning. Certainly this was the case with the 900 series production cars.

Brad, gonna disagree. AFAIK, the only 356 parts which got chromate were the calipers on the Cs. First example bought in '73.

To prove silver or yellow on the air cleaner clamps, can anybody enlarge the photo enough to tell ?
I do not have an original of a factory photo to tell other than what Steven has shown here.

My experience in the military/aerospace industry with yellow chromate is that it is not a very durable finish at all--hot soapy water will remove it. Fortunately that is not something to which our engines will likely be exposed--at least not my engine.

OK, one of you bay area guys who goes to the Saturday morning greasers, tell Jim it's time to pony up! We all paid the (admittedly more than fair) bills, but now you get to step up to the plate (at Oracle Stadium).

No yellow Zinc on any 356s and early 912s. Of course, the yellow is easily removed w/a fine wire wheel and
and refinished w/a Dove Gray or a light silver and clear-coat.
