basic horn button question ('68 Custom) non-chrome??

[KevinK7]

I searched, but I'm only finding the reproduction horn buttons ("Chevrolet Division") for the '67-68's in bright chrome.
The original button is more of a 'brushed/satin' look, but does not appear chrome. (photo below of repro and my original)
I did order one off Ebay, where the seller listed one as chrome and another (that I ordered) did not say chrome. I just received, and it's bright chrome. I contacted the seller and he states that's all he's aware is out there.

To note, I have seen photos of originals, that admittedly look a bit chrome on the perimeter, but brushed in the center area. My original albeit a dirty and old, sure doesn't look like it was ever chrome.

Does anyone know is there is actually a satin/brushed cap reproduced?

Thanks in advance,

Kevin
