It's about 30 odd years old, and has a simple cam arrangement in the body
of the handle that stops the handle turning when the door is 'locked'.
Needless to say, there's no manufacturer's name, and I can't track down
anything similar.

Is this the standard arrangement for privacy handles, rather than a
separate mortise lock? Obviously, I'd prefer to fit a like-for-like
replacement, rather than a complete new lock assembly.


Sounds like one that I replaced recently. Aluminium construction with a
thumb turn below the handle. About a fiver from local builders merchant.

Something like this?
