I was asked to sell a 20-key Hofbauer "Tanzbär" accordion for
a fellow MBSI member.  The accordion is in excellent shape but has
been un-touched for several years.  It plays when plugged into the wall
outlet, but I believe the battery is dead.  Also, some valves seem to
be sticking or not working.

Has anyone ever worked on these instruments?  I can't see any screws
holding it together.  Can the lead-acid battery be replaced or improved
with a more modern battery unit?  Thanks for any advice!
