Hi,  in reply to Sam's question, the person probably meant a Gulbransen
Registering Piano.   This is written on the plate in the spoolbox and
does not have any significant meaning at all,  just part of the sales
pitch, supposed to register the touch of a pianist or something.  Every
Gulbransen, both normal and Recordo,  that I have seen here in
Australia (and that's quite a few) has this plate.
