Hi All,  Kim Bunker here from playerpianos.com  I am currently working
on a style F Orchestrelle by Aeolian and I have been searching for the
schematics for this and other unusual player musical instruments.

I discovered that if I'm able to get the patent numbers, not the
patent dates, I can retrieve the original mechanical drawing of these
instruments.  Does anyone out there know how I can obtain this
information: finding the patent numbers of the instruments on-line
somewhere?

I have checked with the U.S. Patent Office and discovered that you
actually need the patent number in order to search the actual
documents.  If so, I'll be able to create a data base for this valuable
information to our industry.

Thank you for now, Sincerely yours,
Kim Bunker
