PS2 Version Identifying

[sidother]

I can't tell what version of US PS2 I have. The Serial number starts with a U 2 and has 8 screws on the bottem. I first thought that it was a Version 3 PS2 becuase of the U 2, but I've read on web sites that Vesion 3 PS2's have 10 screws on the bottem. Can anybody help?
