Wayne van Zwoll wrote a very good story about Al Biesen in the current issue of Sporting Classics. He mentions Roger briefly but doesn't mention he has retired.

As with all Sporting Classics stories, the photography is superb.

IIRC Roger had some replacement work done, hips or knees. After that I do not think he ever took on any new work, just tried to clean out the backlog.

That was a good article. Also the one about the engraver Rachael Wells.
