[CAUT] Mystery 'O"

[James Grebe]

Hello Caut list.
I have posted these same questions to David Kirkland of Steinway-No reply 
and to various other members of the Pianotech list never getting an answer 
so I will try this list.
     I have one client, a church, with a Steinway "O" from 1905 that is a 
regular "O" except that it does not have the duplex scale.  I have sent some 
pics to help you get an idea of what I am referring to.  My questions are 
these.
1.  How long did Steinway do this?
2.  Why did they do this?
3.  Why did they switch back to the duplex scale.
Thanks in advance.
James
