This is the bridge from a moon 4-string bass I used to own. * The screws to fix the bridge are not included. * The original strap pins, which were removed when I changed to locking strap pins, are also included. These also do not have screws. I replaced the bridge soon after I got the bass, so I've kept it in storage. I don't anticipate using it in the future, so I decided to list it for sale in case someone else could use it. The string spacing is 18mm as measured. \#Moon \#ElectricBass \#GOLD
