Anything specific you want to know? Any particular reason?
btw it's an EC-155 not AS: AS designators stopped when Aerospatiale merged with MBB and became Eurocopter
PS. the bit about the Middle East is correct to a point; it was one not "them" and I think you may find they were outside the FLM operating envelope (limit is +40 C), unless they were doing a lot of night flying! So perhaps their gripes about performance were not entirely justified.
