To my knowledge, I don’t believe the ‘+’ was ever adopted as the official nomenclator, at least never in the US. The RFMs simply refer to the variants as “AS 350 B3 Arriel 2B” and “AS 350 B3 Arriel 2B1”. The current model designation is “H125”, however the RFM is still entitled “AS 350 B3e”. IMHO, in the US, the manufacturer has always clouded the differences to the point of it ostensibly being a contributing factor in several accidents.
