I think the 43 rarely ever gets any sapphires it is mostly just a volvo b7tlwright gemini  today i was on the 43 which was 7488 seen 7490 on the 43 & 7493 on the 43 and abit of a rarer appearance with 1575. Arriva probably should have thought before having the e400 sapphires branded for the 43 as well as the 44 & 45. And when the 43 is actually  a sapphire 7522 never shows up on the 43 and is constantly the 44 & 45.
