I am glad Julian Dyer has these files.  If you have not heard live or
via recording these rolls, they are wonderful.  I second everything
Julian has to say about them.  I own all that Mike made available via
New England Music Rolls and believe them to be some of the finest done.
As Julian indicated, Mike transcribed them -- mistakes and all -- from
Jelly Roll Morton's recordings.

I know many of you know Mike and have seen his site, but there are
always new folks, so take a look:  http://www.doctorjazz.co.uk/ 

If you have an interest, I would let Julian know.  These are great
rolls with historic significance.
