Yes, there were three versions of the IBM wireless mouse ignoring the wireless ScrollPoint models. Slate blue, silver and grey and completely coated in rubber; earlier ones are ball based. You can also swap the wheels, so the silver one could have a red wheel put in it:
Since they're PS/2, you could also incorporate a wireless mouse on something super old.
Receivers don't have much to them despite the large enclosure:
But I find that they chew batteries down pretty fast (the ball ones iirc may not drain as quickly but don't quote me on that). So.... there's really no point.

That looks like an acorn mouse i had , if you know RISCOS you know it uses a 3 button mouse as standard.
Those three button ones are most definitely Logitech. IBM had the Logitech Chroma (which I am fairly certain came out after than the Irish three button one with the 'circle' on the centre button) stuck on with an IBM logo in both beige and black. I happen to have a black IBM-rebadged Logitech Chroma paired to the right of the ThinkPad:
There are late 3-button
IBM styled mice (89P5069) which actually upright state "manufactured by Logitech for IBM". What's unusual about that is the fact it actually states who manufactured it and it's always these darned 3-button mice. I'm not a fan of them myself... and the Logitech Chroma really isn't my cup of tea; I'm just keeping it for collecting purposes to ultimately sell some day.
