I have two catalogs of Roesler-Hunholz organ rolls for the "Artistouch"
player mechanisms they built.  Each catalog lists basically the same
selections.  One catalog is titled "Concert Model Recordings" and the
second "Standard Recordings."

Can anyone out there tell me what the difference was?  The numbers of
the selections in one catalog do not match the numbers in the
other ... nowhere close.

Your help would be appreciated.
