I really don't care how the other guy spends his money, and I know that if you want to restore something with original parts, you're gonna pay, but this seems crazy. Especially considering that when these are mounted, the markings are hidden, and new ones go for less than $15 a piece.

I noticed a set of High Standard factory grips for almost $200.00 on ebay.
I guess it does not hurt to try!
