I purchased this TLS brake plate from Dunstall back in the late 60's. It looks like a Triumph on the outside, but inside it is a different animal. Can anyone shed any light on this?
For comparison, the Triumph inside is below:

Note the Triumph plate has the cams wedging apart both shoes top and bottom. The Dunstall cams work on one shoe only, while the opposite shoe is on a pivot. The internal ribbing of the brake plate appears to be the same on both types. I am thinking Dunstall modified a Triumph brake plate, but what shoes did he use?
The brake is a great TLS, with no tendency to self-augment. It was a drop in fit to the original Norton SLS.
