GB Arrett brake parts

[funk2monk]

I am now starting to re-build my Armstrong Consort but unfortunately I’m missing a few bits off one of the brake levers.
Looking for the small brass cable housing that fits into the lever and also the retaining clamp from one on the levers?
Any pointers for help please.
Photos from the complete lever.

Try Dave Marsh at UCC Maltby, Rotherham.

Is the clamp similar to the Weinmann ones ? If so do you have any spare that you can rob ?

What does the brass ferrule look like from the other side ?

GB brakes have non-metric threads, or at least the Sport 3 does. Weinmann, I assume, are metric.
