Perhaps I'll post another of him playing on a one row and another with C#/D..
BTW he's about 6 ft 4 in. and has huge hands... the box I smaller than the typical Cajun made box.
The Jewell on the Button Box site is most definitely the Pointe Noir if you are looking for a classic Cajun made box. It would not matter that Dick Richard used, or did not use, butt joints.. there's magic in his accordeons.
Years ago I ordered a box from him and shortly thereafter his wife dies so we put it off for a while.
