Spotted...

Guy on sort of teal coloured track bike with red chris king headset and front disk brake, in in Broadway market yesterday. Very nice build, amazing frame, that he said he built himself. Said he was a metal worker then rode off before I had a chance to ask him to build me one... or teach me all he knows. Who is this welding god, anyone know?

^think it was fillet brazed.

Teal sounds like the Wilkinson - ridden by a quite a tall dude?

Did he look like this?

No disc brake and not teal or the other bits you mention. He is quite tall, though, and he built his bike himself.
