Can Anyone ID This Old Bridge?

Different saddles but that's no big deal. Gotoh makes one like that too, but I wouldn't expect that makers mark on the back for the Gotoh. I'd expect one in Kangi. The Gotoh picture is below the Fender picture. The Gotoh logo is a tweak to the bridge, it wasn't always there.

 

If you're going to use it, once you get it slicked up, be sure and apply some lube to the threaded bits (the pairs of saddle height screws and the long screws to adjust string length). For this sort of thing, I prefer one of the firearm wonder lubes, BreakFree. They'll never seize after a slight application, and it's harmless to finishes and plating and electronics.

You might want to drop a drop in each saddle height screw hole, just in case: Often someone used almost the right size Allen wrench, an if they're chewed up a little, better they should turn easy if required.

 

That's good advice re: lubing the threads. My setup guy turned me on to a homebrew concoction that's part Vaseline® petroleum jelly and part Liquid Wrench penetrating oil, but lately I've gotten pretty excited about NFS Race Grease for all my lubrication needs.

 

BR, I like the BreakFree, as it's harmless in this use, plus, it's absolutely the S**T for our guitar playing friends as it pretty much sweat-proofs Floyd Rose and all the other wiggle sticks. And you only ever have to use it once.

 

my guess is a bridge off any one of a dozen different budget import basses from the '80s or '90s. "jin ah" is a brand of cheap hardware you'll often find on these instruments

i like the raw brass saddles and tracks for the screws though and it looks like a beefy bridge overall
