This 3 button mouse replaced the Acorn Mouse Mk2 and was shipped with the A30x0 & A4000, and maybe with the A5000, so I have called it the Acorn Mouse (Type 3), The mouse is made by Logitech and is a model M-PG15. The Acorn part number is 0914,000.

The pictures show:

The top of the mouse showing the 3 buttons.
The bottom of the mouse showing the Acorn serial number (93-AGB22-1025950 - AGB22 is the product code for an A3020), the mouse ball with a removable collar which enables you to clean it, the Logitech label and the 4 circular plastic pads which the mouse slides on.
The inside top of the mouse showing the buttons which press the button switches.
The mouse with the top cover removed showing the 3 switches which detect the button clicks at the top, the ball, rollers and sensors in the middle and the mouse cable termination on the right.
