Long treble strings.

[Jon Page]

I also has a 1938 M in the shop, that length on C8 is 48 mm. A sweet 
piano, sold :-)

Also, on the S, there is enough negative rear bearing to slip a piece 
of paper under the strings
and on the exposed lower adjacent notes (broken strings) the string 
impressions stop about
1/4" behind the front pins.
