Rosenkranz baby grand?

[Andrew and Rebeca Anderson]

I'm to go evaluate a Rosenkranz (spelling correct to photo) baby 
grand in the near future.  It has a serial number of 13268 which is 
web-dated between 1878 & 1892, ERNST ROSENKRANZ Dresden, Germany.  My 
piano atlas is coming up way short on this one.  The oral history 
reports it is an old German piano.  It has two pedals, turned legs 
and a carved (through) music desk.  Appears to have original ivories 
in decent condition.  It is described as all playing (but out of 
tune).  Perhaps someone from across the pond can shed a little light on this?
