Looks ok. It is the older model of Sr300. Decent basses and the bridge looks original from what I remember. Just give it a good going over and make sure the active controls are working ok, the neck looks ok etc. If the bass is all ok, you got a decent bass for your cash.
One thing. If you play fingerstyle and rest your thumb on the pickup, due to the shape of the pickups following the radius of the neck, if you jam a plectrum between the body and the pickup it gives you a better anchor for your thumb.
