No, polished aluminum isn't chrome, and I don't think anyone would confuse the two. There were definitely a few variations in the finish of the PS1s.
These chromed ones are I'm sure just something John did when trying to figure out what he was going to do with his finished product early on.
I'd trust John Grado to know if the ones he's selling on ebay are 1 of a kind or not. And I can't imagine two of those godawful abberations would have been made.
I was just being an ass. I'm thankful for anyone who serves, on our side or the other in any given conflict. If you care about your way of life enough to fight for it, you have my respect.
