Rotorhub lists the [35!] Bell 427s in a production database but it seems that via there at least no-one has thought to have a go at the 407....
It may be noteworthy that in a recent issue of Flight it seems the manufacturers are going to re-launch the 427 again..... and offer IFR!
The [via] Rotorhub list suggests that most 427s remain on the US and Canadian register.
