How do you relic a new P bass bridge cover?

Hello everyone! I own a 62 P bass reissue made in 93. The bass is fantastic, and has naturally reliced over the years. It is missing the bridge cover, but the only replacement I can find is the chrome models sold everywhere which in my opinion would look out of place on this bass. I was recently told that the best option is to buy a new gold bridge cover, use metal polish to remove the gold which will expose the nickel plating underneath. Then suspend the part in a sealed container over vinegar for a day or so to mimic aging. My question is 1) Has anyone tried this, and if so was it succesfull?
2) Is there any retailers that sell a nickel plated part?
3) What method do those who sell relics use to get the aged look on this part.
I am not looking for a very worn out apearing part, but rather a well taken cared for aged part if that makes sence. Thanks for any replies..

 

I have looked, and will continue too, but I haven't seen one.
