    Not 100% sure that's a Chater Lea Headclip though, most of them had notches around the top, but I've also seen ones with knurling.

    If you clean up the top race/clip assembly you'll probably find the makers name.
    Brampton are another possibility, I think TDC made them too, as did some of the larger bike manufacturers, the one on my Claud is marked CB for example.
    If it is a chater lea, you'll be onto something good. another quick check would be the chainset - if that's chater lea you'll be laughing!
    Here's a shot of the chainset on my full-CL equipped track bike...
