Similarly, in [[starling]] temperament, which tempers out [[126/125]] a ~[[9/5]] minor seventh is equated with ~25/14, which combines with a 10/7~[[36/25]] diminished fifth to give a 9-odd-limit essentially tempered chord:

[[Septimal meantone]], which is well-represented by the historically prevalent [[quarter-comma meantone]]), tempers together all of the above chords, so any of the those interpretations may be relevant for dominant seventh flat five chords found in common-practice music.
