DCC , I don't know how I missed such a splendid and intellectual article
The 9-90 is one of my favourite movements and forms a large part of my collection.
I did a similar write up a few years ago but the focus was on the 9-90 movement only
Thank you so much for your time and effort in putting together such an informative article.
Julian
