Dutch builder, primarily known in the UK for coaches, both separate bodies and integrals. They do build buses though, and have even built double-deck service buses for both the UK and Ireland in the past!
The later Atlanteans were of the improved AN68 type, in this case an AN68/1R. Again, an unusual body was fitted, this time by Van Hool McArdle who also built some similar bodies on Dominators for South Yorkshire PTE.
This example has been preserved in the later two tone green of Dublin Bus, somewhat more attractive than the single tan livery.
