This 3 button mouse replaced the Acorn Mouse Mk3 and was shipped with the Risc PC, so I have called it the Acorn Mouse (Type 4), The mouse is made by Logitech and is a model M-P30. The Acorn part number is 0914,002.

The pictures show:

The top of the mouse showing the 3 buttons.
The bottom of the mouse showing the Acorn serial number (72-ACB25-1015512 - ACB25 is the product code for a Risc PC 600), 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. This mouse came with my original Risc PC 600 which I bought in 1994.
