Every couple of months we go through the bridge thing on this forum...
Unfortunately, or actually from my standpoint, fortunately, the bridges are all different sizes between the series. All of the Korean-Made, Czech-Made and USA bridges are different sizes.
Why is this good? Well if the Euro and USA was the same size, you'd have people replacing bridges and trying to pass off Euro models as USA models on Ebay. And PJ and I already have enough to do helping people now with the old, "I bought this on Ebay or from a pawn shop... what is it?"
The NS-2A bridge is the same size as the current Legend Series Bridge.
You can buy a gold one here:

I know the picture is of a black Legend Bridge... but you'd be ordering a gold one.
As far as gold Schaller Tuners... those older Schallers have an anchor screw that is 90 degrees from the body... meaning if you look at the headstock while the guitar is sitting in a rack, the anchor screws come out of the tuners to the left or right... towards the center of the headstock. Not below the tuners as the current ones do.
They are Schaller M4 tuners and run $134.79 a set. You can get them here:

You can buy any bridge from us you'd like, but the Euro and USA bridges are too large for the routed hole on your NS-2A and you'd risk destroying the finish and the playability of the guitar if you tried to route it out larger.
I'd recommend going with the Legend 4 gold bridge if you really want to make the switch.
Thank you JP for the resource URL!
Ironically, I'm about to switch the gold hardware on my Euro4LX-Classic out to black. As a bassist who uses a pick (a lot) I anchor my palm on the top front of the bridge. I've worn through the gold finish and honestly, my Euro4LX-TW-35 has the black bridge and tuners and I like the look better.
I'm thinking about ordering the USA NS-2 I'm gassing for with the black USA bridge and tuners as well. It's one less thing to have to polish/keep clean. Lately, time has been something I don't have a lot of.
