Correct 69 Z/28 Shift Knob for console cars

[69RALLYSPORTZ28]

Is the original 69 Z/28 Shift Knob for cars with a console, a zinc die-cast that was then chrome plated?
Anyone recently had a plating shop restore their knob to back to as new condition?

I had one chromed years ago. Came out nice & still looks good....Joe

Had mine chromed less than a year ago along with the handle in WI. Think it cost around $150 to $200. Both came out perfect, was afraid there might be flat spots or signs of rechroming but there wasn't any. They were adament that they used triple plating process.
