Responding to Mr. Gerber's question, the organ seems to be a homemade
instrument.   As such, it really doesn't have a model number.

I believe he's asking for what style music roll it plays.  From the
pictures, it seems to have groups of 16, 15 and 9 notes.  It was
difficult to say how many trombones and/or flue basses it has, but
there don't seem to be many.  From this information, I believe it plays
Wurlitzer Style 150 rolls.

There will likely be no manuals available for this organ, since it's
probably unique.  The Style 150 tracker bar scale and information as to
possible tuning is given in the MMD Archives.  I cannot hazard a guess
as to its worth.
