Tom, I am sure you know, but for anyone who doesn't....
"Triple Chrome Plating" does not mean three layers of chrome. I refers to the three step process--copper, nickle--chrome. After the item is cleaned ( REALLY cleaned), it is given a coat of copper. Blemishes and pits can be repaired and soldered, and re-contoured as needed. Another flash of copper to even up the appearance, a final buffing and then it gets a coat of nickel to make it bright and protect the copper. The chrome is VERY thin and adds that final sparkle and ( as noted above) a slight bluish cast, and protects the nickel from tarnishing.
I think if you nickel plate something, you will need to periodically buff/ polish to make it gleam.
