Vintage style Jazzmaster/ Jaguar bridge from a Squier guitar. These bridges are known for their design flaws, however this one is fairly sturdy. The grub screws and height screws were treated with "blue" Loctite, which keeps them from unscrewing but are still easily adjusted if desired. I've never had the height screws fall down or intonation screws rattle free.
It has less than two years of use so is in great shape.
