Could have been 19/50 but i think it was 18/45. We discussed bailout before the dive and compaired gas but at the time of writing this I had forgotten exactlywhat it was. I was on 18/45 10ltr 240bar and Ali 80 of 50% 205 bar. He was on an ali 80 of 18/45 and a Ali 7 of 50% both arround 200bar

The tank was marked up badly so i couldent read it the way it was mounted but I knew his deep bailout was in the big tank and shalow bailout was in the little tank so it was a no brainer just trace the reg back to the big tank.
