I am working on a style C Wurlitzer orchestrion which is equipped with
the standard five-tune single roll frame.  The owner would like to be
able to utilize the longer 10-tune rolls.

I am unfamiliar with the specifics of the larger frame and wonder if
anyone could supply me with particulars regarding gear ratios, take-up
spool size etc.  Any help would be greatly appreciated.

Thanks
