if you want to be, need to be period correct, the first set in CHROME are required for mid 70's and earlier.

The second set is stainless steel, functionally the same, actually better as they don't rust, sometimes a bit different in perimeter shape but not correct for the period correct crowd, actually a bit on the low side for the Chrome ones, perhaps due to the rusted fasteners.

I did not bother to look at the third set, took too long to load.
