I have an old Gigabyte KM-6150 keyboard and an old Dell keyboard - both have some faded buttons but work fine
There is also an old mirrored Satechi mouse - although not sure if it still works.
All are destined for the household tip but thought I would offer them in case anyone locally wants to take them for spares or some computer DIY
Two computer keyboards (faded buttons) and old mouse (Kirkley NR33)
