Default Cordless telephone with a dial.

The first cordless telephone I saw had a small dial on the handset, I am fairly sure its owner brought it back from the USA.

Has any one ever seen one, or could point me to an image of it on the Web?

How do I use that information? It's not a valid URL.

I still can't find a reference to it, but I think I've found the dial
https://en.wikipedia.org/wiki/Trimli...ineExposed.jpg

If not that, then one heavily inspired by it.

The dial I saw had 10 equally spaced holes, to be honest I don't remember it having a moving finger-stop, but I suppose it must have had for a trigger to toggle, not sure about a slipping-cam type though.

The moving finger stop on the Trimline dial doesn't trigger anything. It allows the dial to turn through a larger angle for a particular hole (when you dial a '0' the dial turns through more than 1 revolution I think).

There were at least a couple of corded telephones that used said dial, but I've never seen a cordless one.

Not directly.

Perhaps it would make more sense if I'd said
"I suppose it must have had for the trigger to toggle,"

As I understand it, the "trigger" is the correct name for the gizmo that toggles around when the dial reverses direction, and transfers the profile of the toothed wheel to the dial pulse contacts.

The larger angle required is precisely to accommodate this action.

A nice bit of lateral thinking by Western Electric, or should that be angular thinking.
