I have a Vintage Marx & Marx Liberty Harp that is HAND MADE. It does have a split on the right of F Key, no scratches.  For the age of this instrument, to me it is in really good condition and the graphics are MINT, along with the Keys & Numbers in Mint Condition. Even on the right front of the Harp, the wording as to how to tune it looks like it has never been used.

Ask any questions you may have and   THANK YOU  for looking at my HARP.  Will try & get some better pictures so you can see the Graphics better.
