no..but it does have to do with the damper system..and again, it is a 
damper system I have only seen one other time in my tenure of piano

What type of system might M&H have used in 1915?

PS - I do not think I am throwing y'all off by stating the type of 
damper system..again, I have only seen this type of damper system once 
before...on a 1864 S&S Style2.
