Edit: I just weighed the bridge and believe this is the brass version, not aluminum.
Chrome 4-string Hipshot A-Style Brass Bridge
3-hole mounting version - lines up perfectly with middle and outside holes if your bass is drilled for 5 holes.
This came off a bass I recently purchased and swapped all hardware to black.
In excellent condition with little signs of use.
Specs and dimensions can be found here: Hipshot A-Style Bridge
$75 shipped in the continental US.
