They have that hardware option: http://www.andersenwindows.com/products/series/400-series/

Might want to try and remove one lock and see if you can figure out who makes it or call Andersen and see if they sell the replacements.

Woodwright 400 is a current window. Go to a local Andersen dealer that has the hardware boards on display to see what their satin nickel looks like. Obviously, the handles won't match the older ones but the finish should be close.

Thanks - it looks like their upgraded option for anything other than "stone" and "white" is $75 a window. That is quite an upcharge.

@Kristy Bible, if you're still around, do you mind sharing how your Andersen Woodwright windows have held up? We are window shopping and this is a contender though I wish factory stain was an option. I am not a huge fan of the "stone" or "white" sash lock either, though the "gray" balance channel (maybe called Jamb Liner) appears to "match" the "stone" sash lock fairly well. The other option for the balance channel is "white," I believe.
