History and Basic Info
The Royal KMG is the successor to the Royal KMM. It is basically the same machine but with tombstone keys and a gray paint job. KMMs came in gray, but not as often as KMGs. The "Tombstone Keys" on these machines match those of the Henry Dreyfuss Designed Royal Quiet De Luxe.
Just like the Royal KMM, KMGs are very solid machines. These will most likely need something like a drawband replacement and some deep cleaning.
