This is from an Aria Pro MA series Stratocaster. I disassembled an Aria Pro Stratocaster I had to repair another guitar. I removed this part at that time. It was working without any problems before removal. It's a used item, but there's no rust and only some minor dirt, so I think it's still usable. There are also 6 screws. You can buy it immediately. However, please refrain from purchasing if you are sensitive to the condition, as it is a used item.
