On the most used keys the button has worn the hole in the lever such that one has only a small amount of metal left before it wears right through. On this particular button the play was around 1.5 to 2mm compared with about 0.5mm on a little used accidental.
(The legs have splayed a bit but that isn't a big deal and could be straightened with pliers.)
On first inspection the levers are close to knackered and I can't see an easy way to repair them. Can anyone suggest either a repair strategy, or offer any ideas about spares or a replacement action?
The box owner does not have deep pockets.
PS couple of typos fixed and second photo added
