1972 saw ETS's first T6H-5307N buses delivered. These buses featured standee windows, and double folding exit doors which were a first on a fishbowl for ETS. These buses were numbered 536-569. #552 was a prototype for the black Firestone bumpers. Most units were retired from around 1999-2002, however a handful stuck around until early 2008. They were: 536, 542, 559, 560, and 562. #s 536, 559, and 560 were the only units rebuilt into the blue and silver ETS scheme.
