What tools are required to dismantle it?

Hi

I was trying to dismantle this camera on the weekend to clean the sensor.

I was going well, managed to remove all the minute Phillips head screws and got the back off. Then I came unstuck. There were 3 really small Torx screws holding the sensor cover on. My smallest Torx driver is in a kit I brought from you for Mac repairs, it is a size 6. Any idea what size these in the camera may be? And do you have a kit with the smaller size Torx drivers?

Thank you

Keith

PS It is a fantastic camera but obviously has dust/pollen on the sensor as there are "splodges" on the screen and on photos that move around.
