Someone had filled the the threads in with braze and it was really well done, that's why I think it was the frame builder. This was made in 2001, right around when threadless was taking over the market, so it all makes sense.

Anyway, it is still working great. I did have a local pipefitter sleeve and braze an extension onto the fork because it was too low for me. So now, half the stem is clamped above the original fork. Either way though, this bike and fork have been nothing but solid for 25 years.

All steel of course.

Done carefully it's probably fine.
