Can anyone identify this tubular latch please?

Thanks but what neither tell you is the height of the case! I thought I'd found the ideal one, but it transpired to be 510 high, my cut recess is 400mm high so I would've had to have cut out a further cm, burrowing deep into the door! Sure, I could email each company in turn, but you might think the size of the case was of importance, too, wouldn't you, assuming not everyone is fitting a new door!

This, however, is of more use to me! All relevant measurements given.

that one can be used in, say, a bathroom and have a Legge turbutton fitted which locks it. There is a slot, and the turnbutton has a metal strip which either turns horizontal, so the it passes through the slot, or vertical, which prevents it moving. A handy trick, not often seen.
