==19 equal temperament, Costeley== 

 I can certainly look to see.  As far as I know Costeley only wrote one or two pieces using microtones, when he was in contact with Sandrin who kept in touch with Vicentino.  (I've heard some music by Easley Blackwood in that temperament, from 1980-1983)  Good work on tuning/temperaments by the way!
