I recently bought an 1960's(?) Vintage Hardman player whose case has
been refinished.  It came with about 60 (mostly) QRS rolls, + a couple
from AEolian.  The decal above the keys (there is no fallboard) reads
"Hardman" with the corporate seal, and the name Hardman Peck in smaller
letters.  I'm assuming the original decal was destroyed in the
refinishing process, and that this is a copy.  My question is this:

   Is this piano a "Hardman Duo"?
   
The reason I ask is several of the rolls that came with it advertise
the "Har dman Duo" on the leader.  I know players are sometimes
difficult to date using the Pierce  Piano Atlas, but if anyone can
help, I will try to get everything off the top and look for the serial
number.
