Fw: unduplexed Steinway

[Pianoman]

> This morning I tuned what appears to be a Steinway (0).  This is from 
> 124xxx
> serial number (1907) that has no separate duplex bars in the back scale. 
> Instead there is a curved raised ridge where the duplex bars would have 
> been.  I have seen probably about 6 of these in my life.  How long did 
> these models exist and what was Steinway's reason for this change during 
> this era?
