Has anyone had any experience in the adjustment of a Concert roller
organ when the problem seems to be the mis-alignment of the cob when it
shifts back at end of rotation.  I'm novice enough to ask for help
before I attempt a cavalier operation.

in recent months all of your help has allowed this novice to restore
an Ariston, purchase a nice roller organ, a Playamonica and some great
rolls for my Duo-Art.  Anyway many thanks for all the help.
