And meantime while we look into the M K M house's story, I became interested in li'l 8417 Sunset, sitting forlornly with its additional "1/2" on its single line between the other, multi-line, addresses on

LA Times, May 2, 1926
LA Times, April 6, 1960
So 8417 went from being a "palatial home" to being where cocktail waitresses lodged (no disrespect to cocktail waitresses intended).
